Vintage St John's ambulance medical poster Respiration.
This is a lovely example of the St John's ambulance photographic medical posters. This one is titled on the back "Respiration" and also has a stamp saying "To be returned to general stores dept. LMS Derby". This originally came from the first aid department of the LMS railways.
The poster measures 85cm x 55.5cm and has the original wooden hanging batons. This is in very good condition with no tears and just a couple of creases on the canvas backed printing.
