Gay 90s Songs in there!
"This is an amazing opportunity to own a fantastic lot of rare, original Optigan discs & song books - all from the early 1970's.
This lot is 25 pieces in total -
12 discs & 13 books.
9 of the discs are in mint condition, STILL SEALED in the original factory shrinkwrap.
(The shrinkwrap of one of the sealed discs has been torn, but the side where the sleeve opens remains intact)
2 of the discs ("Bossa Nova" & "Easy Does it wth Vibes") are opened & appear to be in fantastic condition. The only flaw I could see is a tiny indentation on one of the discs.
There's also another disc (not pictured) that I found in my vinyl collection & am including in this lot. It's in a clear sleeve & appears to be in excellent condition.
The songbooks vary from good to excellent used condition, some yellowing, shelf wear, & a few have minor pen/pencil marks."
