I have an old post card from teh French Soudan, maybe 1900-1907, can somebody help me with the publicher?
Thank you.
The post card is here

Hello,
I'm not sure if this helps but there is an unused copy of this postcard on delcampe at the moment ( item 69646844). To the lower left corner, obscured by the stamp on your copy, is a circular logo with the word Phot to the top and the company name A B & Co or perhaps A B & O to the centre of the circle It's possible that the logo is something added by the seller to protect his image rights but I don't think so.

- that appears to be the case from the previous reply and a search against the full title 'SENEGAL et SOUDAN - casseurs de Pierres' on delcampe reveals that there are 5 examples currently for sale at the moment! - the price varies from 4euros to 15euros! - and no further clues to the publisher unfortunately, but they all have that circular logo in the bottom left corner -

I did a similar search on ebay and found no examples of this postcard ........

good luck

Thank you !
I have to loock for thIs A B & Co!
It looks like AB & Cie...
i find some postcards in the Arhive National du Senegal with this logo!
