Note that on the pink version, the front and rear images are glued on, whilst on the blue version, they are merely printed. ANTI 2001 version also has images glued on.
Full ANTI 2001 copies exist - i.e. sleeve, labels and matrix (matrix shows it to be an EMI pressing with "U" suffixes). The original Island/EMI-distributed pressing was available for at least a couple of weeks in early May 1973, as per Photos of Ghosts (advertised first week of month in music press - whole page adverts). I'll hunt out and scan labels, plus the relevant portion of the rear sleeve (I can't do whole LP sleeve scans).
There are likely more hybrid copies out there, as per ANTI 2003 - i.e. ANTI sleeve with WEA sticker over ANTI cat no, plus crossed out ANTI matrices and added WEA ones.
I bought an incredibly battered copy of this with pink sleeve a few weeks back. The K 43501 cat number does appears on the dead wax, but sleeve and labels use a cat number ANTI 2001.
Added sleeve cover and label images. My copy seem to have a German produced cover (with cat. number 86 901 IT on spine and cover back), with UK labels. Not sure if my copy qualifies as a UK issue? Feel free to trump these with UK cover when scans are available (or move them to a German issue).
