This is cool, thanks to OP for submitting this.
In the past I have ordered topographic maps from Raven Maps and they really are excellent. Not cheap, but you can get plain paper suitable for framing or laminated if you want to write on them with whiteboard markers. I have a giant one of the USA, plus a few of states I've lived in.
