These cards were packaged four to a pack in C3PO's cereal (Canada, 1984). There were 10 stickers numbered 1-10 and 10 cards numbered 11-20 in the set randomly packed with 4 cards in each.  Two cards are visible on each side of the pack and 2 stickers are between them but not visible in the pack.

This is a sealed package of 2 cards and 2 stickers.  This package contains card 17 and 19 shown.

It also contains 2 random card stickers from 1-10.  The possibilities are in the 3rd photo showing 2 of the 10 stickers you could get in the sealed pack.

These cards are very hard to find in good condition and very rare mint in the sealed package.

Will be sent with tracking.
