About what year were these photos taken?

Hey guys, I bought a couple cool old prints of Wrigley Field for my condo, but the listings don't have a ton of information about the year they were taken. I figured there might be a history buff or two in here that could clue me in. I figure people might ask questions about them, so I'd like to have the background.

First one, no date range was given by the guy at all. I figure someone will be able to tell approximately when it was taken based on the cars in the picture (I think that metal railing the kid is leaning against is still there).



Second image, it says c1930s. Not sure if anyone has a better idea based on the street cars and other buildings.
