Something really collectable: The Horrors of War trading cards:
http://www.the-for...hemera/R69CARD.HTM Probably the most Famous Gum Card set ever issued. This card set was issued by Gum Inc. starting in 1938. The illustrations are colorful, detailed and gruesome. conceived as a 240 card set about The Chinese-Japanese War, The Ethiopian War and The Spanish Civil War. The set proved so popular that an additional 48 cards were added about Germany and the beginning of World War II. The addition of these 48 cards to the set did not prove as successful as Gum Inc. anticipated and hence the last 24 cards and in particular the last 12 cards have proved very elusive to collectors At $1000 or so for a set I'll never own one but the images can be found on the net.
