Black Beauty was a Sprague trademark. At the same time the paper versions 
were made they produced a high quality film version that was used by HP and 
others, all Ive tested are still fine. They have red lettering.
Production years of both can be found in the yearly Radio Masters.
The Bumblebee style were also Sprague and a lower cost version of the BB for 
catalogs and cheaper OEM's
