Lot of German Schwanenburg Margarine Receipts

Big lot of Schwanenburg margarine receipts. It is an interesting mascot choice for the company, sort of the Mrs Butterworth of margarine, selling her margarine at what appears to be an outdoor market in the sun. There are quite a few receipts here some have damage or tears, all are filled out. These look to be pre-war. I think I saw a 1926 date on one.
