I have a velvet tone record in a Columbia Records (Columbia Grafonola)sleeve. The sleeve has pictures of Grafonolas on the front and on the back are ads. There is a statement that says the record speed is 80 RPMS. The 2 songs are Lindbergh(The Eagle of the U. S. A.)and Lucky Lindy, performed by Jack Kaufman. Q: Is the sleeve good? Is 80 RPMS correct? Would you know a value?

Thank You, Paul
