Wow! So cool!
Is it a print on paper or on a metal sheet? Metal sheets usually have all the words in reverse? The number 2/20 is probably for the number/edition but could also be a date February 1920. The engraving depicts trenches, rows of crosses, devils, coffins, animals, injured people but more important tanks and artillery thus post WWI.
There appears to be letters inside the engraving bottom left _ ANAER_.
