AFICIONADO STAR WARS MYSTERY: KENNY BAKER IN CHICAGO!

Sometime between 1977 and 1978, Kenny Baker, in his US public appearances for the lovable droid Artoo Detoo, took part in what would apparently become a controversial STAR WARS related OLYMPIA beer promotion in Chicago, without the prior knowledge of LUCASFILM, which had the slogan: "The best thing to come out of a can since R2-D2."

Does anyone out there have this advertising image, or more information about the advert in general? Apart from the ONCE UPON A GALAXY BOOK written by Alan Arnold from 1979, and J.W. Rinzler's recent MAKING OF EMPIRE book I'd never previously seen or heard about this.

If anyone can help, please get in touch.
