Child's Cup?

This little cup is about 3.5" wide and a little over 3" tall. the fruit appears to be incised and glazed in different colors - cherries, a pear and an apple. the background looks like spongework or something. i picked it up for $1 from Goodwill a few wks ago. i think it's pretty old, but i really don't know much about this kind of pottery. any help appreciated, as always.
