The Guardian reports that Steel Panthers posters promoting the "Balls Out" album are banned for being "overtly sexual". The ASA received four complaints about the poster which shows a barely dressed woman caressing herself while holding a pair of silver balls.
The record label Universal Island used the "we're mocking stuff from the 80s" defense and said that the ads were meant to "poke fun at the ridiculousness of the attitude to women, outfits and music in that [1980s] era".
They also pointed out that the posters are meant to be "ludicrously over the top and not meant to undermine women". Cliff notes: "c'mon, we're only joking".

The ASA on the other hand didn't agree, and said the poster was overtly sexual when taken as a whole.

"Given its placement in a range of public locations, we concluded that it was likely to cause serious and widespread offence, was unsuitable to be seen by children and therefore was not appropriate for outdoor advertising," said the ASA.
