SYMBOL IMAGERY??? Pottery Pitcher (McCoy Lost Glaze?)

WHAT IS THIS SYMBOL/ IMAGERY??? Marked USA on bottom. The glaze reminds me of McCoy Pottery's "lost glaze". Not sure. Purchased in ZANESVILLE OHIO. Maybe an end of the work day employee piece? The symbol/ imagery looks like it MAY have been hand carved in the clay ... could've been in the mold though. Do any of you fellow pottery lovers know ANYTHING about this piece? Interesting. Thanks for looking!
