KPS45A is the first Kenner card variation which features a Palitoy
sticker on the back of the card. These stickers replaced the USA address
for redeeming special offer mail aways on a variety of the Kenner cards
from the ESB and ROTJ line with one for Coalville in the UK. The
special offer in this instance is the Star Wars Action Figure Display
Arena. The sticker is shown enlarged below.
This is the rarest of the Palitoy stickers seen on Kenner cards, with only a couple of examples reported.
