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.
Nightcrawler was the "New" X-Man with the most guest shots for the longest time before Wolverine surged ahead of him in the 90s!
His appearances in Amazing Spider-Man #161-162 soared in price, first because of the Tailed Titan then because of the Punisher! He later co-starred in Marvel Team-Up #89, again the first "New" X-Man to do so!
On the ASM #162 cover the kink in the cable Nightcrawler is hanging from is an error. The cable car must weigh much more than he does, and there's no kink where it is. The cables should probably be much thicker, too.
