| Nice collection. A major Boston used bookstore used to have a ton of these (ca. 10 years ago). I always looked but never bought. They were a bit pricey ($5-10) and my money always found another set of books.
I'm glad you have them; they suit your interests very well. |
I remember seeing these in hobby shops when I was a kid. Of these I have found a couple in flea markets, one in a yard sale, but most have come via eBay.
