The Pink Floyd Arnold Layne Mega Rare Us Tower W/l Promo 7 Single Syd Barrett

Up for bid: A very rare White label Promo of The Pink Floyd 7 Single Arnold Layne b/w Candy and a Currant Bun released from Tower Records 333 in 1967.
Label is marked Promotional and Not for Sale .
Record condition is rated only VG due to the vinyl imperfection seen in picture 3.
This would appear to be some kind of warping due to heat, but the other side is without blemish.
This vinyl would rate a STRONG EX if I were to grade it unconservatively, I dropped it to VG just due to that visual appearance as both sides play through beautifully and clearly.
The standard tower promo sleeve is VG only Wish I had the picture sleeve to go with this...
.
Thanks for looking, and good luck
