Welcome. All I have for John Price is 13, Sandgate Road, Folkstone, Kent and trading between 1913 to 1920. He did well not to go out of business during the War. If only in business for a short time his output was probably quite small and limited to local sales. It might be well worth e-mailing Folkstone Museum https://folkestonemuseum.co.uk/ I have often found local museums very helpful in such circumstances. It can be quite amazing what they can add to research. Good luck. Lagopus…..
