Newbie has a Stax promo question

Haven't really posted much of anything on here, just check every now and again for some good info and an interesting read. So hello all, & thanks for all the great info I've gotten from this place, hope I could help out from time to time.I found this Booker T one sided promo white label record on stax stamped for in store play and titled "FUNKTION". No art work on the sleeve, just the band name, title, and "for in-store play" in plain jane black and white. It's got six songs on one side and the other has a nice checker pattern etched on it. I tried checking a couple discographies but I'm figuring promo vinyl doesn't make onto these lists cuz it's not listed anywhere. Anyone seen this around? I know it's kinda weak to ask but I'm dying to know the value on this thing. Any info would be much appreciated.-J

Anyway... it ended up being a Springsteen bootleg. Bollocks.
Never seen the Booker T thing. But I'd listen to it first.
