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

Apple-shaped potholders made by my grandmother Maria Antonia Ludovici Martinez (1905-1991); source of pattern unknown, perhaps improvised, in what feels like cotton.  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.  It looks like the fronts and backs were crocheted separately, then crocheted together, with the green leaves and hangers crocheted last.
