I'm thinking same beer, different can. The Rainier site says "winter jubilee can" and Wikipedia gives some history: "From 1952 to 1964, Rainier came packaged in a series of decorative beer cans known as the Rainier Jubilee Series. First in the series were a set of Christmas cans marketed in late 1952 and again in late 1953; these cans are rare and highly collectible today. The Christmas cans proved such a success that Rainier's use of decorative Jubilee Series cans continued for over a decade, with thousands of different designs. Most of these are not as rare and collectible as the Christmas cans, but the "reindeer" cans (which were sold only in Alaska), and the first pull tab Jubilee cans (made only in the last couple of years of the Jubilee Series) are also considered rare."
Since we're talking about Rainier, there's a nice little celebration in Georgetown tomorrow as the "R" gets raised into place. Think I'll drop by. http://www.restorether.com/
Since the Rainier brand is owned by the same folks who own a bunch of other brands, including Oly and Peeber, not only is it the same beer as in the regular Rainier cans, but probably the same beer that's in the Oly and Peeber cans!
