Frankoma Andrew M Lester White Buffalo Trivet

Rare Frankoma trivet commemorates the birth of a white buffalo (bison) on the ranch of Andrew M. Lester.
Searching extensively online, I have only been able to find two others which have been available for sale in the past year or two. They don't seem to be listed on any of the regular Frankoma collectors' sites.
Diameter: 16.2 cm. This particular trivet is in perfect condition with no cracks or chips. Glaze is completely undamaged. Only one felt pad shows the slightest damage.
I am "liquidating my own estate," currently raising funds for my initial set of robes and travel expenses to be ordained as a Tibetan Buddhist monk.
