It might not quite fit into this topic (maybe a stamp collecting one?), but I just read over at
Newsarama that there will be a series of stamps from the USPS in 2006 featuring DC Comics superheroes. Apparently, 10 heroes will be represented, along with 10 stamps featuring "covers" from their comics. Here is the list:
1) Superman - Superman #11, 1941
2) Green Arrow - Green Arrow (Vol. 2) #15, 2001
3) Green Lantern - Green Lantern #4, 1961
4) Wonder Woman - Wonder Woman (second series) #22, 1987
5) Batman - Batman #1, 1940 (with Robin)
6) The Flash - Flash #111, 1960
7) Plastic Man - Plastic Man #4, 1943 (with Woozy Winks)
Aquaman - Aquaman (third series) #5, 1989
9) Hawkman - The Brave and The Bold #36, 1961
10) Supergirl - Daring New Adventures of Supergirl #1, 1982
Might have to see if I can pick these up next year. More details and pictures at the linky above.
