Reproduction of an old Italian Alfa Romeo guarantee sticker printed on vinyl cling that fits inside the glass facing out. Translates roughly as "Super guarantee, engine 100,000km, paintwork 2 years". (Proved to be fairly optimistic in my humble opinion!). Pride comes before a fall... 

The chap that came up with the idea for a sticker died in mysterious circumstances a few years later, found with a rusty Alfasud sill rammed up his orifice....Sorry I made that up!
