Two vintage Duncan Imperial Trompo spin tops, new on card + empty card

Description

A lot of two brand new vintage Duncan Trompo Imperial spin tops sealed on the original cards plus a third empty card. I believe these tops date from the mid 1980s.
The packaging of the two new tops is in excellent condition. The domes are undamaged and sealed and the cards are unbent with sharp corners, albeit a bit dusty.
The empty card is a little battered, with a few wrinkles, please see photo
