The original artist for this concept will be impossible to find and is probably dead. You can find artistic neighborhood maps of basically every city. Some are more text based (like this one) while others are more picture based. I know I've seen text-based versions of the Baltimore neighborhood map for probably a decade and I'm sure it's been around for even longer. I've seen similar in other cities (https://www.amazon.com/SEATTLE-Neighborhood-typography-available-collected/dp/B01A6IENGW - random city that popped into mind and first result of the first search) as artwork, both prints and woodcut. You can even find cutting boards, magnets, etc.

Which artist ripped off this concept and added a spin to it? Now that's a question that could probably be answered. But it's probably better to call it a derivative work. The Etsy shop listed here basically grinds them out assembly line style.
