When did people start passing out flyers to get people to come to their club or dancehall? The earliest I have come across so far is this card in Southwark Local Studies archive, advertising 'Dancing every Evening in the Gorgeous Al Fresco Rotunda' at Anerley Gardens. (not far from the Crystal Palace). The gardens were were open from 1841 to 1868, and featured a hotel, tearooms, a maze and a bandstand (see my South East London history blog for more details).
Does anybody know of other early examples of flyers?.
