I laugh every time I look at this strip. Mr Mullet seems very in love with himself. From the deliberate, alternating poses, I think it is his luxuriant face-fuzz that he is out to capture in all its glory.
It is quite surprising that he let go of this set of photos. My guess is he gave them to a girl he fancied and she didn’t value him or the photos enough to keep them.
I am not sure where these photos originated, probably the USA. I’d say from the colours and the type of booth strip the photos were taken in the 1990s.
