Here's a nice slide of Knott's Berry Farms Pan for Gold attraction, June 27, 1963. Those are some pretty authentic "cast members".
Got your box of crayons ready? Here's a great Knott's Berry Farm coloring book from 1955. The cover and illustrations are very similar to the children's book "The Knott's Berry Farm Burro in Ghost Town" (link).
Only a couple of the pages were colored in, nice job staying in the lines!
Come back on Bonus Sunday for the entire coloring book, you better bring a new box of crayons!
