I made lots of flea market finds in the 1970s.
Quarter books, 50 cent books, dollar books.
There was one guy who would set up every week.
He had a big three ring notebook with dozens of plastic sleeves that he'd always put out on one of his tables.
In each sleeve, back to back, was 1950s horror and Sci fi comics (except EC).
Dozens of them. Brain Bats of Venus and the like. All in nice shape.
I loved them, but the prices were exorbitant. $12, $15, $18. Brain Bats was $35!
I tried on numerous occasions to buy the whole binder, or to get more reasonable prices on individual books or groups of books. I don't think he ever budged on price.
I can't recall him ever selling anything at those prices in those days.
Wonder what ever happened to them/him.
