It's all one photo

Look closer. Top right is a walkway roof

Exactly. Top right is a building which partly covers a poison ivy stone wall, standing in front of a street lamp and some yellow-leaved trees

i refuse to believe. I can see 3/4ths of it... but it's actually the bottom left/right that has me tripped out. That vine should grow more in the right frame.

Guess that's the trick. The photographer used the coincidence that there's no plants in this part of the wall and now all he had to do is shoot the photo from a perspective that perfectly lines up the building's edge with the stonewall's
