The seller doesn't state an opinion as to when this was produced, but I think this interesting and large item was made during the later 1950s through the early 1960s. The benign imagery is representative of that period. The Chase Candy Company has been in business since 1876, always based in St. Joseph, Missouri. (Their best known product is the Cherry Mash.) Given the simplicity of the design I feel $595 is on the high side. However, the seller is open to offers, so if you have room this may be a good acquisition.
11/10 Update: This sold for $545 to a very good home in Pennsylvania.
