Just in case anyone is interested, there's a copy on ebay at present of the 1954 Derbyshire Yearbook, the first one produced.
Going for 24.99 opening bid (which is a bit steep to be fair) but they usually go for £30-40 and its only the third one I've seen come up.
Good chance for the serious collector to complete a set. Thankfully got my copy (after years of hunting) about five years ago and it was like getting the Holy Grail!
Not that I've ever got that, you understand...
