There is this scene from one of my favorite shows that brightens my mood every time I see it. I even have the song from that scene on all of my spotify playlists. So I want to take a photo from that scene and have it printed quite large (I'm thinking probably around 16"x20") and have it hanging in my home office.

I don't know how this works with copyrights and all that. Will places like Wal-Mart print this image? What would be the best way to have this printed in such a large size, and also not cost an insane amount?

I have already looked around online trying to find one to purchase (print, poster, etc.) but I can't find anything.
