Humour lettering

Snail mail

Produced by unknown when the Internet was becoming popular in early 1990s in the UK. Idea was to stick to envelopes – there was an art form called Mail Art in which artists would embellish envelopes with all sorts of stickers, designs, drawings. Anyone have any? Is it still being done? (See also posts on typography and the postage stamp here, and here and also here.)
