A good old fashioned bike logo for you today, from Hercules bike co. One of the local second hand bike shops brought their stock onto the Nottingham campus the other day, and this old 'commuter' stood out as the oldest... and most interesting!

Really nice lettering, just like on the Harry Quinn frame.
A great old Peugeot bike logo on the head tube.
Super clean design on the headbadge logo. Quite unlike most of the other much busier old bicycle logos of the 70s and 80s.
This particular one is a 20 inch wheeled, folding shopper bike. This were strangely popular back in the day in Britain, I guess because of their low cost and ability to tuck away in an awkward place.
