I’m not sure exactly where or when this stadium was purported to show up in time or geographic location, but the picture was taken in 1938.
This elderly gentleman seems taken with the design of what is clearly a venue for baseball only. It is an interesting design for baseball. I’m guessing it would have been hitter friendly. Look how the foul lines are cut off by the seats in right and left. There would have been two pesky poles in this stadium. Also notice that there was quite obviously no protection from any elements in this design. Finally, being 1938, can you spot what is missing? There are no plans for lights. I looked it up and the first night game in MLB history took place in 1935, but it was far from an overnight culture change where everyone erected stadium lights.
