English: Lemon sponge cake recipe card - Michigan circa 1950 Recipe card comes from my great-aunt's recipe box. She died without issue. The box went to a friend as part of the residue of her estate; friend send it to me. It is my assertion that these cards were produced in the mid-20th century, that no copyright was claimed or renewed, that distribution of them causes no financial loss to anyone, and that I am free to scan them and release the image scans under a CC license or into the public domain.
