Postcard - Tumwater, Washington

"Olympia Brewing Company, Olympia, Washington. The Olympia Brewery is located on Interstate 5, just south of Olympia, Wash. It was founded in 1896 and is often cited as one of America's exceptional breweries. Visitors are always welcome, 8:00 to 4:30 daily, except Christmas Day."

I'm going to guess mid-1970s. Yes, we know, the Brewery was actually in Tumwater, although downtown Oly is clearly visible in the distance.
