Mastro’s April 2004 catalog featured this “only known example” 1966/67 USA Test uncut display box. It was described as an ex-Topps Vault item and was accompanied by that company’s LOA.
The 18” x 25”’ blank-backed sheet, printed in the US on regular cardstock, bears the unfolded, central rendering of a 24-count, 5-cent wax pack counter-sales box. Masto wrote that small proofer’s notes and printing alignment marks appear in the periphery of the sheet.
Lelands first sold an assembled 1966-67 Topps USA Test Wax Display Box (pictured below) in October 2017 for $8070 before selling another for $4555 in February 2019.
And for completeness, here’s a 1966 Topps Test hockey “cello” wrapper. Unfortunately, I can’t remember where I found this one to credit the source.
