question about value on collectible arkansas razorback doll?

was going thru old boxes in the attic for an upcoming garage sale and came across a very old, and probably very rare doll that belonged to my father.

it is a “talking” university of arkansas cheerleader doll with a pull string on the back and it still works…says 3 or 4 different things. it is in pretty good condition considering its age (at least 40 years old i would guess). it is a bit dinjy and yellowed but i am sure that it can be cleaned by a collector.

ANY IDEA ON THE VALUE OR VALUE RANGE? i searched ebay and found nothing like it, which would tell me it is rare since you can just about find anything on ebay.
