I recently found a strange spelling of a reversed S (Ƨ) on an old Japanese matchbox label (late 19th century), in the phrase "MANUFACTURED IN ƧEIRYUKWAN". At first I thought this was just a mistake in the graphics, or perhaps the Latin alphabet was not well known. However, I later found an example where the normal and reversed S occur side by side, in "OSAKANATUƧINSIYA ƧEIZU". This does look like the artist should've noticed. This made me wonder: is this some weird old-style form of transliteration, and what could the difference between those twop forms be? I don't speak Japanese unfortunately, so I couldn't come up with any guesses.
