MapToPoster is a free Python project that you can use to create maps that are worthy of being hung on your wall. It uses OpenStreetMap data to render the same style of striking minimalist maps you see advertised on social media, while giving you control over the exact map location, scale, and colors used.
Once the project has been installed, you can use a simple text command to create portrait PNG files of around 3630x4830 pixels in size (at a density of 300 dpi).

Getting the image is trivial. The real effort is getting it printed and getting a frame for it. And the cost of that tends to be pretty close to just buying a pre-print.

Frames you are almost always best off going to a pawn shop or local art supply store, but even amazon is not a bad choice for that.
Combine that with realizing just how many museums upload high quality scans of genuine works of art and…
Amazon is always a bad choice for anything.
