PopChartLab has a pretty cool 18″ x 24″ poster called A Visual Compendium of Cameras:

A meticulously illustrated catalog of 100 landmark cameras, culled from over a century of photographic history, depicting both professional and consumer models and tracing photography’s history from the first models to today’s digital wonders.

Yours for US$27 for the print only or $112 framed. Unfortunately, I couldn’t find shipping prices to Australia on the website. I guess they’ll show after I’ve put in my credit card, so no-go for me.
