I don't have an exact year for this flyer printed for the opening of Salon 51 in the Murraygate, but I reckon late 70's/early 80's wouldn't be too far off.
As you can see, Dundee FC players were involved in the official ceremony razzle, which got me wondering - did Salon 51 have a special offer on for a blue rinse that day!?
Thanks to DD
