Unknown Circus Match Machine

Unknown manufacturer Estimate 1930s

This is a mystery match machine that has a really neat decal. The decal says "Circus Rider Saftey Matches". It is in "Silent Salesman Too" as a mystery machine but with no more information than what you can discern from the case itself. I have not seen another but I know that there are more than one due to the picture in the book. It is made of cast iron with a sheet metal back.

This example is all original. The paint is a little beat up but the graphics are still nice. I bought this on ebay and don't know anything about its history.
