There is a very substantial collection of Indian war posters in the Imperial War Museum collection in London. Illiteracy doesn't mean no equation at all with the world of print, and illustration.

The German Wikipedia article on Propaganda im Ersten Weltkrieg (apparently w/o English version) includes a few more examples, such as a U.S. poster from 1917 that may have preceded King Kong. Starting from there, one can find more British material e.g. here and here.
Unfortunately, it apparently does not reveal specific Indian propaganda posters either. I think @cleopterist's point about poverty and population levels deserves consideration as the (a) possible explanation: literacy rates in India climbed from approx. 40 to 65 percent between 1980 and 2005 (a bit higher for males alone): they must have been well below the 40 percent mark at the time of the Great War. (Though one might perhaps argue that posters target both literates and illiterates alike, as may still be true for Bollywood movie posters to some extent.)

Indian WWI-recruitment poster was very peculiar. Material benefits, instead of patriotism, were employed to encourage recruitment.
Indian recruitment poster. Urdu translation reads: 'Who will take this uniform, money and rifle? The one who will join the army.
