I found Apollinaire's "It's Raining" to be an interesting mix of text and picture. The words are written in lines down the page, with each letter falling below the one before. Looking at it at first glance, I thought it was a set of dotted lines extending the length of the page, like oddly linear raindrops. Upon closer inspection, it became clear that they were actually lines of letters, and that those letters made up the words of a poem. For me, this called more attention to each individual word, because I had to work harder to read and make sense of them.

The text itself is a poem, describing rain and things that are like rain for the speaker. It has a sad and melancholy feeling to it. The line "listen to it rain while regret and disdain weep an ancient music" was particularly powerful to me. I see this poem as reflecting the very sad and almost hopeless sentiment that people would've felt during and after the war. The poetry expresses this, as well as the image. It's rain, but to me it's also like tears. I think this was much more powerful written in this format than it would've been written in a normal poem, or prose like form.
