Ok, how about this for an idea. We take it in turns to post a favourite (British spelling) comic cover every day. This went really well on the comic fan website that I used to frequent. What we tried to do was find a theme or subject and follow that, until we all got bored with that theme. I'd like to propose a theme of letters of the alphabet. So, for the remainder of October (only 5 days) and all of November, we post comic cover pictures associated with the letter "A". Then in December, we post covers pertaining to the letter "B". The association to the letter can be as tenuous as you want it to be. For example I could post a cover from "Adventure Comics" or "Amazing Spider Man". However Spider Man covers can also be posted when we're on the letter "S". Adventure Comic covers could also be posted when we're on the letter "L" if they depict the Legion of Super Heroes. So, no real hard, fast rules - in fact the cleverer the interpretation of the letter, the better, as far as I'm concerned.
And it's not written in stone that we have to post a cover every day. There may be some days when no cover gets posted. There's nothing wrong with this, it just demonstrates that we all have lives to lead.
If everyone's in agreement I'd like to kick this off with one of my favourite Action Comic covers, from January 1967. Curt Swan really excelled himself here.

Some more fun for the weekend. While there have been different live action versions, so far only Hanna-Barbera has ever had the animation rights at different times. The Addams Family's lone comic book lasted just three issues in the 1970s and was based on HB's first cartoon series. (Image courtesy of the Grand Comics Database.)
Cosmic Boy did get his own limited series, spun off from DC's Legends event, and running for four monthly issues from December 1986 to March 1987.
Karate Kid got 15 issues.
Mon-El got 23 issues (when he was called Valor).

Saturn Girl, Cosmic Boy and Lightning Lad collectively had a 4-issue miniseries:
I remember this comic. At one point, his girlfriend got turned into diamond.

Iris Jacobs thought she was his girlfriend! Karate Kid went to the past to prove his worthiness to marry Princess Projectra!
He actually went back to the 20th century in Brave & Bold #198 to invite Iris to the wedding and broke her heart again!
Three issues 1966-1967
Batman #16
Is that the first time that image ever occurred? Pretty famous.
There's going to be a facsimile of Batman #9 in a couple of months, but I'd rather have this, just for the cover.
