This has a fair bit of wear. The album was released in 1979 but issued in Australia in 1981. This poster was issued alongside it, using Peter Saville's art but layout by Andrew Penhallow.

Size is 68.8cm by 48.6cm.  Ex-record store stock I have had in my collection since the 1980s. 

Please note the lines on the right-hand side are from storage and appear to be where print has worn away (it was squashed for a while). 

Will post with tracking and insurance.
