I'm not aware of any of the DC romance characters being used anywhere since their titles ended, but there were a number of ongoing DC soap opera strips.

As previously mentioned, Young Love featured Mary Robin RN in issues #39-52, and then Lisa St. Claire in #68-78.

Young Romance featured stewardess Bonnie Taylor in issues #126-139.

Secret Hearts starred advice columnist Amy Ames, who often didn't heed her own advice, in #96-109. Then, in the next issue, the ongoing ensemble soap opera "Reach for Happiness" began, running from #110-138! At 29 issues, this is DC's longest running serial. It also ran longer than just about any other series DC launched in the mid 60's.

Heart Throbs had another ensemble soap opera called "3 Girls - Their Lives, Their Loves" which ran for 22 issues from #102-123. Both "Reach for Happiness" and "3 Girls" were written by the same person, writer/editor Barbara Friedlander. 

Girls' Love Stories featured starlet April O'Day from #104-116 (I think?).

The only ones that I don't think had any long running characters were Girls' Romances and Falling in Love.


As for Night Nurse, to piggy back off what tartanphantom said, while it's true Linda Carter sported blonde hair in the Bronze Age, she actually first appeared in 1960 in her own title, Linda Carter: Student Nurse. And in her original appearances as a student nurse, she had black hair, so it seems the blonde was the dye job, not the other way around. The opening page pf Night Nurse #1 makes it clear it's the same Linda Carter, as she is graduating from nursing school when the issue begins. She also has the honor of being in the first "Marvel Universe" crossover - she appeared in Patsy Walker #99 one month after Fantastic Four #1 came out.

I have a bit of a tale to share with a recent  ebay purchase- Last week a copy of Fantastic Four # 112 went up for auction but no one was  bidding on it nor even watching it, although the price was pretty good.  The only two images that the seller posted was the cover and the back cover.

This is a picture of the back cover.



I gambled and placed a bid and won it. I was the only bidder. It arrived today in this envelope.



No hard cardboard to keep it from being bent, and it was placed in this manilla envelope 



When I opened the book I found it to be in G/ G+ shape despite some cover issues. I almost can't believe it wasn't bent on route to my house.



The Captain, this is the book I wrote to you about. 

Yep. I knew it was a gamble from day one. The guy kept describing it as his " uncles" collection. I ended up paying 24.99. I'm tired of paying any more for these books. 

July 28th. From the UK, ordered on the 15th. My fourth Comicana order. Best overall service, although I'm not happy with "Tracked and Signed" being slower than "Standard" these days:


.


I find these two PAD issues equally funny, although it's the second one that usually gets the credit.



More Byrne goodness. Not the best script he's gone over, but he's never drawing again like this.























A fun isolated Byrne issue plus the rest of Simonson's run.



I've recently bought a few MTIOs, so there goes another Byrne issue.

















Getting the best of Stern's run on the title. Or the ones I have a most fond memory of.

























Some Mantlo issues worth keeping (I don't see many of those) plus a bunch of PAD's. No Ace, thank you very much

August 3rd. From the UK, ordered on the 24th:



Another cursed issue (just behind X-Men #137). I saw my order cancelled twice from two different vendors. I finally went with this cheap, low graded copy, which wasn't that cheap due to postage, obviously.

August 3rd. From Barcelona, ordered on the 28th (next day delivery, but took 3 days to ship):















Except for #50 (which I already have in the FF Byrne Omnibus) I think this all I wanted with this series which wasn't already accounted for.

August 4th. From Amazon, ordered on the 30th:





I hope the really complete the Aaron collection. Volume 3 hasn't even been announced and I'm thinking they're going to need at least a total of five, so we're a long way from finished.



Both the Spanish and the American versions can't be found at reasonable prices, so original one it is.

August 4th. From Mile High, ordered on the 7th. Two of the four weeks were for processing, Asendia is the best for overseas delivery, hands down:



The only Conway scripted comic in my collection. Other than the art, the main attraction is the early Wonder Man appearance. He was probably the most intersting Avenger back then.

























The bulk of the Immonen run (not going after the Ultimatum-interlaced issues).

Holy cow, Ozymandias, you just posted 92 separate images of comics you bought. 92 images! That takes a helluva lot of scrolling to get through and also makes for long page loading times (not everyone who browses here is necessarily on broadband). That really is overkill, I'm afraid. Five or six images with 15 or so comics in each picture would be plenty. We don't need a close up of every comic you've bought in an almost 100 comic lot.
