I like this one a lot.
WOULDN'T BUY IT THOUGH - unless i got it signed by a bandmate.
I'd do what i just did.
I'm pretty sure most of them would be unofficial bootlegs. Appears to be Russian, Israeli etc discs.
Also check Discogs and some site called google.
Beyond that I'm not sure
That rings a bell. Possibly with a music weekly IE Melody Maker, NME etc? They used to do this kind of thing for bands like Bowie ('74) through to Suede and Manics ('94)
I recall there are Fan Club messages on this format too.
The eBay listing is actually for a special kind of flexi disc. Although it is listed as Russian, it is in fact Polish. These were quite popular in Poland in the 1960s and 1970s. Their name literally meant "sound post cards".
