Each of these 20 stamps features a comic strip classic. Daily and weekly newspapers have brought Americans cartoons since 1895. It is reported that 86 million adults and 17 million children in the U.S. read the Sunday comics each week! In fact, comic strips are considered one of America's only indigenous art forms. The comic strip and its characters have popularized words and phrases, such as "I Yam Wot I Yam," from Popeye, and even the foods we eat, like the "Dagwood" sandwich from Blondie. Comics have become movies ("Popeye"), and Broadway Shows ("Annie"). This sheet honors comic strips created within the first 50 years of comics, from 1895 to 1945.

My 2¢ is that while they are a decent reference they are a terrible fair market price reference and their stock isn't assembled by philatelists by any stretch of the imagination. Oh if you do poke around there on their site be sure to check out the Rare Stamps section.. If you have any stamp sense you'll quickly know what I'm talking about!
