Through a series of events, I crossed paths on ebay of a cache of Linwood Carter's early items. These items date from his high school years (probably 9th grade) anward to his years in Korea and early fanzine years (about 1954).
I was only able to obtain minimal information, but it seems a "flea market" or estate styled trader obtained these items and put them up on ebay.
An enormous number of images were posted over several months, and sold off one at a time.
I obtained a very few precious items. The rest were stored electronically.
