[Mccoypottery-talk] Yellow Smiley Face Mug

[Jill Bakke/Walter Pancewicz]

First, I just realized I don't know how to spell smile-eee.  I apologize if 
its incorrect.

Second, I just inherited a yellow-smile-ee face mug from a great aunt.  Its 
in great shape and she's had it for many years.  The marks also indicate 
that its the real McCoy.

Can anyone tell me more about it? Years?  Did it come in different colors?
