Crochet apple potholders by Maria Antonia Ludovici Martinez, San Francisco, California, USA

Potholders made by my grandmother Maria Antonia Ludovici Martinez (1905-1991). Source of design unknown, crocheted of thick thread that feels like cotton, with tight twist, with the thread used for the rings being thinner with a sheen; the rings have a stiff support under them, white, probably a hard plastic.  My grandmother used these, and I inherited them after her death--her dishes were the Franciscan Apple pattern, and she had a lot of reds and whites in her kitchen.  The apples (with their stems and leaves) are crocheted separately and appliqued/stitched onto the two-layers of white backgrounds,the red edging crocheting the two layers of the white backgrounds together.
