Indians For Guns

Hi anyone know where I could buy a Authentic 1940s tiger hunting poster or ad in newspaper or similar ?

This sort of add you mean.
I am sorry but these are only available in Old books or old news papers or in net. You need to create your own poster by enlarging it from some computer works shop ( that's what I can say in my knowledge)
May be some antique collector or old and reputed gun shops do have some copy. But it will be a pure luck to get one.

Yes that's what I was thinking Shivaji, vintage old poster.

Bro, better you collect the old adds from different old books and news papers also some available on net. Reprint them in poster size of your choice.
I am saying this because these all were news paper adds. Even if some were given a full page add but news paper ( if not maintained with special care ) after almost 100 years will be in a delicate condition. It will be costly and then again the cost incurred for its maintenance.
Reprint will be fast and cost effective option.
