It's still a good find...I don't know that it is a retro by the way, so don't take my word for it.
I am probably completely wrong but colour on monochrome with possibly an older Mr Goodall made me think 1960's retro...but I know nothing...really
Here are my latest finds off the bay
1894 Nelson's orange essence bottle £3 and a packet of Nelson's No1 photographic gelatine c1923 £1.50
