I grew up in southern California (Whittier), which is pretty close to Knott’s Berry Farm.
Back in the 1960’s, this wasn’t yet a typical theme park filled with roller coaster rides. There was a nice old-time feel to the place, with chickens and peacocks wandering around the parking lot.
We’d visit regularly, and every such trip included a viewing of The Button Collection.
My grandmother lived in Filer, Idaho and collected thousands of buttons over the years. Eventually an aunt finished off the collection and donated it to Knott’s Berry Farm, where it’s still on display.
