For anyone interested, Poundland are currently selling 12.5 inch by 12.5 inch photo frames - or to put it another way, photo frames that are big enough for an LP record
Photo Frame Record
I currently have my signed Iron Maiden 'Powerslave' and King Diamond 'Conspiracy' albums in them, and will be going back to get two more - one each for my original cover Guns N' Roses 'Appetite For Destruction' LP and my original cover Uncle Sam 'Heaven Or Hollywood' (if Chloe lets me put it up!)
The frames are fine for single albums, but you might struggle to get a double album or something with a gatefold release in it
