I won a set w/ the original box a decade or so ago from Lelands
Had 50 cards enclosed.
Here's a scan of a box w/ instructions, it looks period to me.
This scan has the blue tinted version, mine was the red tinted version.
W/ most of the cards being in high grade. Had them graded by PSA and I got grades from 4's to 10's.
W/ the lower graded ones having wrinkles in them.
