Hanging Dish, Walker Potteries #824, Monrovia, Calif., Vintage. According to the Mike Schneider book of California Potteries, Walker Potteries in Monrovia was owned by Joseph Walker. Exact years are unknown. However, it had to have operated prior to 1946, the year Hagen-Renaker was founded, because John Renaker worked at Walker Potteries prior to going into business with his wife and father-in-law. The ending date for Walker Potteries is a mystery, but it seems to have lasted at least into the 1950's. This pretty pink and purple scalloped edge dish is 6 by 5 1/4 . It would beautify the wall of your house or could be used as a candy dish. It has a pretty scalloped purple edge and two holes for hanging on the back.
