Porsche model (time) or date line?
 

hey,
Does anyone know of a time line or date line with all porsche models shown on it? I'm thinking of a long sheet with years running along the top or bottom and where each model started and ended on it?

(i know i could make one up from the history on the porsche website, just wondered if anyone/Porsche AG has already found/done this?)

cheers guys
