Popped it into TinEye. Here's some random references:
https://www.reddit.com/r/OldSchoolCool/comments/5ezhp7/an_ibm_store_in_the_80s/daglpk6/ (comment that links to previous image)
That image was quite popular on Reddit apparently. Some of the reverse image search results name the file things that reference Toronto. There also appears to be a version floating around where someone has converted it to more of a grayscale.
No obvious original source in my admittedly causal search.
