I have a record and cover from the indy 500 w/ back home again in ind sung by singing hoosiers of indiana univ

the cover has the track on the front with the ( 500 ) on it and inside it has stories about the 500 and pictures and on the back it has past winners from 1911 to 1961, listing thier names,cars and top speed. any ideas on what it might be worth or where i can find out the value of it.
