USSR X-Ray Flexi Discs

These were single sided bootleg records made from
discarded X-Rays, nicknamed 'Bone Music'.

However these began to be phased out in the mid 60s because the state allowed
the public to purchase reel to reel machines which sounded much better.

These below and most of the ones currently for sale on ebay
are modern day counterfeits.
