Hi Rhiannon
It is a lovely site isn't it. There's also a link to a page of lovely old French pictures too.

A word of warning.
It starts with a postcard fair, but before you know it, you'll be craving stamps, coins, and the next thing you know. you're immersed in the deep disturbing twilight world of hardcore anorakary. You'll be reduced to trading your wares in smelly town hall crypts with seedy strangers.
