This 1924 child's cup or mug was an advertising premium for Ovaltine, made by Sebring Pottery. It features Uncle Wiggily (often misspelled Wiggly) and Grandpa Goosey Gander arm-in-arm with the "Ovaltine House" in the background. The artwork is signed Lang Campbell, the original illustrator of the Uncle Wiggily books and comic strips. On the back of the mug is Uncle Wiggily at a run with the words "Uncle Wiggily Wants His Ovaltine".
Juvenile advertising china pieces were usually giveaways or very low priced. They were produced inexpensively and were often not the highest quality - the kids cared about the characters, not the aesthetics of their dishes. The mug's handle has a thin, small stress separation at the base which is under glaze and occurred during manufacture. There is crazing, wear to the blue band at the rim, and some pinpoint glaze fleabites at the rim, a couple of which have caused minor staining. There is also some staining at the underside base. The mug has no cracks, hairlines or structural damage but it was apparently much loved and used by its owner.
