This is a view of the Aurora Theatre sometime in the 1950s. And, after doing a little digging, we see that The Tall Texan, with Lloyd Bridges — the Big Lebowski’s real life dad — was released in 1953 (and wasn’t really a good movie). Poking around a little more, we see ads for the movie in the summer between July and August, so it’s safe to say that this photo is from the summer of 1953.
Kilduffs also has some great stuff on the theater. Check it out.
