released on 24 August 79 per BPI (Friday)
the album was originally scheduled to be released before their concerts at Knebworth, but there was delay due to the production of the sleeves
I thought I had an unusual copy, until I noticed it's from Spain..
mine does have two extra small pieces of art under the usual 'stamped' title on the brown bag
plus a nice dark 'LED ZEPPELIN' under the Swan Song logo..
I will upload soon.
I think I'm right in saying that it has a magic paintbrush inner sleeve - just add water and the colours appear! (Not so great for anyone with sweaty hands).
I have added The Brown Paper Cover (Front and Rear)
The Cover (Front and Rear) Version A of Six Variants indicated on upper spine
The Inner Sleeve Front and Rear and the Label Scans.
Later pressings came without the bag.
