I declare an interest in that I deal in folk-related material.

I had a complete set of folk roots from no. 1. to recent 2006 0r thereabouts.

I advertised them on Ebay and out of how ever many years two issues sold - one to an Oyster Band fan and I can't remember the other.

I gave the rest away. Not my best ever deal.

So the short answer in :- unless you are very lucky - not much.

Sorry.
