Captain George Henderson was the proprietor of the Memory Lane nostalgia shop on 594 Markham Street, Toronto. He "had excessive facial hair, a twinkle in his eye and a desire to provide anyone who entered his shop with their most desired item." as one fan wrote on her blog.
Henderson was also one of the earliest kings of the comic strip reprint business until King Features took him to court and put him out of the business. Henderson was apparently unaware that Alex Raymond's work was still under copyright. His piracies cost him from 4,000 to 10,000 dollars in fines, sources disagree on the exact amount.
In a very short Macleans article (more of a squib) of April 1969, "Got a vintage "Batman"? See the King of Camp," it says,
"At 39 he is Canada's King of Camp and an ardent comicollector (sic) who got that way by chance three years ago, when he whimsically decorated his book-store with old comic books he had found in his sister's basement. "A man came in and picked up a Batman from the display and peeled off five $20 bills from his money clip. I immediately closed the store and went down to the States to find out what the business was all about." Now he's selling 15,000 used comic books a month, including surprising quantities to newly hooked youngsters."
Captain George had a worldwide reputation with his various reprints selling for for 25 cents in Canada, the US and Europe. his international reputation was not surprising, few people had ever seen the comic strips Little Nemo or Krazy Kat, they seemed to be irrevocably lost to history. Hell, most boomers had never even seen a Captain Marvel comic book.
Henderson launched three fanzines in 1968: Captain George's Whizzbang, Captain George's Penny Dreadful, (a free weekly still running in 1982), and Captain George's Comic Book World. Huib van Opstal* kindly provided content listings for a few of the titles >
