With a 9" x 24" background scene & "over 30" transfers, this set seems to be a variation on the Thomas Salter "Ewok Village" box, but not a direct copy.
If I had to guess, I would say that the original Thomas Salter sets came before the popularity of the Wicket character was evident, & then when it became clear that they warranted it, several "Wicket the Ewok" sets were released.
Naturally, all the copyright dates are 1983, because that was the year the film was released.
The range includes "Wicket the Ewok: Ewok Village", "Wicket the Ewok: Ewoks at Play" & "Wicket the Ewok: Ewoks at Home" (a Thomas Salter box set which we hope to be able to show you very soon, since I just pointed Craig Spivey at a set for sale & he duly took the bait).
Don't forget that this range also led to the Free Gift transfers in Marvel's Star Wars Return of the Jedi Weekly.
To establish the precise relationships between all the various different Ewok transfer products requires a steady hand & nerves of steel. Just saying.
