Frisco FFF Stamps

Below is a scan of a stamp that I purchased off ebay and an image of the four stamp block.

 

Neat find, Keith!

Now I'm wondering how these may have been used: on any waybill tacked to the car itself, or on a uniform bill of lading? Regardless, it appears to be a marketing tool first and foremost.

Best Regards,

 

I have a block of four of these stamps as well. I have 'em framed and on a shelf - pretty neat looking.
