Wow, that’s interesting, thanks, Philip! I took the title right from a Pinterest post when I was looking for old snuff photos, I didn’t have any idea how many shops they were running! It’s a shame seeing snuff decline so far after the rise of cigarettes, and as you mentioned Smith and Sons lasting into the 90s, but probably finally closing their doors due to increased anti-tobacco legislation in Western countries around that time.
But hey, pipes started to go the way of the dodo bird with the introduction of cigarettes and then had a resurgence, snuff will have the same and will keep on keeping on!
