Or simply someone passes away and their family puts it all in garbage bags and sends it to a landfill. A rather ignoble end to the erotica associated with an otherwise tenaciously dedicated group of fetishists,
I once bought a whole cardboard box full of nothing but torn out illustrations from erotic/sex novels as were printed in the 1980s-90s, pulp covers, inside illustrations etc. A really good find which I bought dirt cheap at a specialized secondhand bookstore in Brussels. I was thrilled as can be since he box contained around 1000 illustrations.
There was a story behind it though. I am always curious about how such things end up for sale in shops and I asked the proprietor how he came to have it for sale. He said it was brought in by a young couple in their late 1920s, they were either niece or nephew to an old uncle who had recently died. They were either sole heirs to his stuff or had been regulated to clean up his house. In any case they found boxes and boxes of printed erotica, magazines, books, prints etc in his garage and didn't know what to do with it all. Apparently they started burning the contents until someone noticed, they must have gotten to talking because the curious neighbor or passerby, told them about the specialized shop in Brussels that sold all manner of old and secondhand erotic/sex publications.
So off they went with what was left, which turned out to be a large cardboard box and several small shoe-boxes of stuff and brought it to the shop where I bought it all in a snap, just quickly glancing through the contents. There were even naughty books going back to 1914, hastily reprinted with well wishes for French soldiers going to the front in the Great War. Not something you find everyday.
Despite the find, I more often wonder about the boxes that were burned before the nephew found out about the specialized erotic bookstore. What did they all not contain that is now lost forever? Such a shame.
