I have a lot of WDCS, Four Color, Lone Ranger, Looney Tunes, War and Romance comics but I think Horror comics probably are the most popular non-hero comics. Disney collectors used to be in abundance and Duck Four Colors could still be hidden away in many collections but Thing, Vault, Weird Tales of the Future, Crypt and many other horror titles are sold on the open market or bid on privately by a large number of vocal collectors. Timely/Atlas collectors usually will have more horror in their collection than Tessie or Joker. EC is probably more popular than Archie but early Archie and Pep are more scarce. OK, just some thoughts...
