Why is this pressing of Deep Purple's 'Burn' going for so much?

I came across this on Ebay: http://cgi.ebay.co.uk/DEEP-PURPLE-BURN-1974-PURPLE-EARLY-UK-PRESS-LP-EX_W0QQitemZ200311325402QQcmdZViewItemQQptZUK_Records?hash=item200311325402&_trksid=p3286.c0.m14&_trkparms=72%3A1701%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318

Why is it going for £37 when it's not even a 1st press? Is there something about it that I don't know of?

Just eBay hysteria?

 

That's nothing. Check out this promo copy of In Rock:

No bids for In Rock yet though

 

Exactly. That's like the guys who post MFSL gold CDs for $799.99. Just for show.
