It's a pretty set with vivid color drawings. 1960 Primrose Confectionary as Gary pointed out. 50 card set; there are four sets on the PSA registry, none of which are complete, but I couldn't find a PSA pop report for them. Kinda weird.
Got it - it is a little challenging to find the pop reports for overseas cards. Some of the UK Kane cards (Kings & Queens, Motor Cars, etc.) are in the European/Foreign cards category; the Disc Stars set is in the NS section.
