This gentleman paid a professional photographer to take his picture with (likely) his brandnew Imp. The photographer numbered these photos and put his stamp on the rear:
Peter R. Smith
37, Newcastle Avenue
Calderbank, Airdie
phone no. Airdrie 4638
Airdrie is just above the M8 from Glasgow to Edinburgh, 25 miles from Linwood.
This is photo 123/5
I am guessing it is an Imp de Luxe in stead of an Imp as the owner was willing to pay for extras like white wall tyres and overriders.
