Good Evening Everyone From Tennessee!

I have a prarie green guernsey creamer 93a
that we are trying to research.it is an advertising’
creamer with s.w. annual meeting 1950 on
one side and the other side reads okla.city .
It seems to be rather obscure in that I searched
forty pages of frankoma on e-bay and didnt
see one.It is 3 inches high and two inches across
bottom.It is the red ada clay and reads frankoma
on bottom.

Any ideas as to current book price on this piece?
thanks in advance for help.

Pete
