After wading through several screens of eBay garbage, I was stopped short by this great design. Although this example seems to be in poor condition, I haven’t seen this Beistle creation offered for sale for a long while. It was issued in the very early 1960s. Later in that decade, Beistle reissued a double-sided version. I would change its RSIN from “3” to “2.” Given its condition, a bid at the opening price of $35 surprised me some.
07/27 Update: This sold for $51.
