You can just google image search the poster, save the image, upload it to a poster printing website and print it.

I've done it 9 times and I've even gotten a 10 x 5 foot poster made of the park city ski map.

Recommendation on a solid online printing shop?

Bay Photo, https://bayphoto.com. Good prices, great service; I use them for my own work, at sizes beyond what I can do in my own shop. Next time they disappoint will be the first.

I've used https://www.uprinting.com/ for all mine and it has been great so far.
