American Indian Pottery, Clay Jar w/ Raised Corn, Navajo, Signed A B (#5039).

Jar/pot approx 4" high.

Navajo artist Lavina Bartlett is well know for these pots with the raised corn. 

This jar is signed A B. (see pic) so we aren't really sure if this is one of her pieces.  It is very well made with only a 1/8" chip, shown in the last pic
