Oh yes i remember, the box is very rare Al but i'm sure you know it very well! game cards fairly common do to close-out release
they were patterned from 1951 red/blue backs, that box set was extremely limited back in 1968 i did see them once
at a newbberrys dep store i used to go to here in the west coast, but only that once, the cards were introduced in 3rd series wax and cello packs like the ones in the piccs which is important to know! because there is a number of series
1 & 2 packs, around with the game card which means there are either home made or fake!
