A Tantot was a humerous illustrator, cards illustrated and presumably published by him appeared with
both his signature and a monogrammatic AT logo.
During WW1 Tantot had published patriotic cards bearing his name (A. Tantot) on the address side with no logo.
The ATV logo evidently was created after the business was taken over by his widow. Cards include illustrations by Xavier Sager and also many more by
Charles Naillod, typically of Sager-like ladies often in humerous situations.
Some of the cards by Naillod have just the printed letters A.T. in place of the monogram logo.
