Hervorragende Arbeit !!!!!

excellent Antonio
A very fine old paper - is it an Agfa type?

Thanks Alfred. On literature I have found there was a Brovira 124 but it's so rare that I never saw one around.
This box is branded Max Klinke Fotohaus Berlin, but actually I don't know who really made it.
In those times, Agfa used watermarks on the back of the papers but here there is nothing.

Thanks for answering me Antonio.
I bet it's a paper made by Agfa
BN 124 that is an Agfa code..

nice!
