I bought a collection of genuine first issue Stiff singles from a lady who was given them at the time (including "New Rose" - score!) and this was the only one in a company sleeve, the others had picture sleeves. It has the word "Delga" on the rear flap without a dp logo which I thought was unusual. Hope that helps?
Same here, Bodston - but by the time of BUY 15 (the next Stiff without a pic/custom sleeve) the logo was being used widely on Delga's output (I think). It just struck me as being a bit 'out of time' for when this 'Basher' single was first released.
Every 'first issue' copy I've seen (including my own) comes in the company sleeve, printed by Delga. This has their distinctive 'dp' logo on the back - which otherwise doesn't seem to have been introduced until 1977 (the earliest Stiff pic sleeve to include it being, I think, BUY 17). Earlier pic sleeves of course just bore the word 'Delga' in a plain font.
Did anyone here obtain the single back in August '76? Did the earliest company sleeves just have that plain font 'Delga' on the back?
