Copyright Aid

And if this was a print from a book 1900 would copyright be lifetime of author plus 50 years. Thanks your help.

So a photograph taken in 1900 would then become life of the photographer plus fifty years?

Thanks Andy
And am i correct in thinking anything prior to 1911 would fall under the 1842 act lifetime plus 7 years or 42 from publication.

Hi I have various cabinet cards and CDVs All pre 1900. In most cases the Photographer and studio is listed. Can i scan and reproduce the images? are they all out of copyright?
