"Look For the Blue Eyed Indian" Inscription.
The bottom of the mugs have what appear to be Mold Numbers Embossed on the bottom as follows:
These items may have been made by the Anchor Hocking Company without the traditional Anchor on the bottom.
Mugs are 3 and 3/8 inches tall and hold approximately 8 ounces of liquid when completely filled.
Thanks for looking.
