What one issue of a comic book is your Holy Grail, no matter the price or rarity would you like to have for your collection?
In other words, what one issue of a comic book would you like to have, but you do not currently own?
Mine would be Avengers 1. Originally got it from a neighbor lady, when her boys grew up, in about 1970 or so.
Traded it away seven years later to a collector was a adult.
Drats, I wish I still had it!
