Japanese editions, mis-pressings, stuff that nobody bought...
the list goes on.
Personally I have a soft spot for the Japanese I Want It All 7" and the Golden Boy Radio Edit Promo 7", but then I'm very materialistic...
of course vinyl have its value... but not the standard issue from UK or USA. Usually promos, colored, picture discs obscure pressing from ASIA or S. America, test pressing... have a look at my site :) link
wasnt there a pink vinyl somewhere? i think it was the single for Too Much Love Will Kill You B-side with We Are The Champions...i saw a very rare poster for it on ebay and it said on the iten desc. that that single was a pink vinyl...
but i thought there were others?
