Q:I have an 11 1/2-inch Barbie-type doll that actually gets a tan if she's in sunlight. Her hair color is reversible from blond to brunette. I can't find any information on it. Can you help?

A:Your doll was made by Ideal and is not one of the Barbie dolls, which were made by Mattel. Ideal made three different dolls that "tanned" when exposed to the sun. "Suntan Tuesday" is 11 1/2 inches tall and has hair that swivels to change from blond to brunette. Her boyfriend, "Suntan Eric," is 12 inches, and her little sister, "Suntan Dodi," is 9 inches. The dolls came with stickers that could be put on the dolls before "tanning" and then removed to reveal the lighter skin under the sticker. They were made for Ideal in Hong Kong in 1977 and 1978. Your Suntan Tuesday doll is worth about $40 to $70 with its original box.
