I've been baffled by the lettering for years, one theory I came up with was that the letters were in the pack in the same way the letters are put into seaside rock (sweet sugary holiday treat on this side of the pond - see link attached) I'd imagine the letters would be lost during the twisting though. I'm intrigued and look forward to reading the post by Steve when it's ready.
