I try to be honest in this webpage, I do not show pictures from:
- Important Curta sellers from Europe, US and other countries.
- Current auctions, usually I show the pictures around 1 or 2 month after closing.
- People that make me a request to remove it.
- Pictures not related with the simple spirit of this page: Just show Curtas!
I do not sell or trade this pictures, I only want to collaborate with the Curta fan community with this large picture database.
In the first year of use of this webpage I received 2 claims for picture copyright (actually I believe it is the same person!) from Passau, Germany. If you think I may infringe any picture copyright or want I remove a particular Curta's pictures, just tell me!
