I've been looking up Ticky Snacks and came across this, which actually places the photo as pre-war:
This company was founded in 1926 by Henry Telfer Thompson and his wife, trading initially under the name "Ticky Snacks Ltd". The company's "mission", apparently, was to supply meat pies to the masses; its lead product in the early days was a meat pie called the "Ticky Snack" - "Made as Muvver makes 'Em".
The standards of cleanliness in the company were, at the start, dubious; but profits were reasonable. Thus it was that "Ticky Snacks" came to the attention of J. Lyons & Co - the British tea giant, controlled at the time by the Salmon family - who purchased a majority interest in the company in 1933; by 1938, "Ticky Snacks Ltd" was a wholly-owned subsidiary of Lyons, and abandoned the "Ticky" name in favour of "Henry Telfer Ltd".
Lyons investment (principally in a new factory) greatly improved production conditions - although, for a time, the Lyons group as a whole were reluctant to associate their brands (produced under pristine conditions for the time) with those of their new subsidiary.
The war was really good for Telfer. By 1940, the company was supplying huge quantities of their cheap and (more or less) cheerful pies and other snack products to publicly funded or supported enterprises contributing to the war effort, including various food support programmes, workers' canteens and - not least - the British Army. Enormous numbers of Telfer's pies were fed to the troops returning from Dunkirk who, after what they had been through, were no doubt duly grateful. Many of them would have been familiar with the good old "Ticky Snack" as a treat enjoyed in happier, pre-war days.
