My uncle, Richard Webster, started collecting comic books when he was a kid, and in fact one day in about 1948 he came home with boxes of hundreds (perhaps thousands) of comic books he had bought for 5.00 from a friend. My Grandma promptly made him throw many out - not knowing that they would be worth 100's of thousands of dollars someday.
He did rescue a few hundred, and his collecting began. He soon expanded his collection to include signed original comic strip artwork and newspaper strips which he kept until just before his death 3 years ago. He sold some, and donated many many many boxes of his comic strip collection (truck loads, I'm told) to The University of Michigan - 1 million strips! Among his favorites was anything Peanuts by the late Charles M. Schulz. When I visited him about 20 years ago, he displayed some of his favorites, that were signed by the artist, and most that I recall were Peanuts and Dick Tracy.
I'm reminded of this because of some items being sold right now at Onlineauction.com such as this fantastic signed sketch of Snoopy, which was just sold by jnhcollectibles for $265.50!
