Solo ARP Demonstration Record - Blue Vinyl

[Mary]

Hi! I am a new registrant. I am a collector, and in an estate sale I found a blue, very light weight vinyl, Solo ARP Synthesizer Demonstration Record, probably from the 70's. It is a 33 1/3 RPM Recording, and the sample music sounds great. It Is the size, though of a 45 RPM Record. It is in its original cover.

Can anyone tell me if there are collectors out there who can share information (interest, value, etc.) on this demo?
I appreciate your help! I have pictures, but I am not sure I should attach them.

Regards,

Mary Van
