I was at a show in Canada yesterday and bought three records that were marketed by Revell from their 1/32nd scale kits in 1969. (you would send35 cents to Revell with a coupon from the kit to get the record).
I got the Wildcat, Thunderbolt, and Zero records. These records are about the size of a 45rpm disc, but they are to be played at 33 1/3. They're in very good condition and a steal, I think, at the price that i paid for them.
Anyone have an idea of value? I checked ebay listings, and found none either in active or in completed auctions.
