Fender framed retailer patent lithograph 1956

Product Name: Fender framed retailer patent lithograph 1956
Fender framed patent lithograph 1956 tremolo device For Stringed Instruments Clarence Fender. Patent issue April 10 retailer 1956 Father worked for fender. Made at Fender and fender branded wood finish isn't uniform and a bit rough . Looks like it was something they were testing out to make. Don't think they put it into mass production because I looked online and I couldn't find one like this. Pretty sweet looking though. Would be perfect for the music lover that loves all aspects of guitars including the business and entrepreneurial aspect of the humble beginnings of the company. Maybe it's one of a kind. If you have any information on what it is a message would be great! Comes with box Pretty certain that it is a lithograph Thanks for looking!!.
