Great quality finish on the poster! You can tell by holding it the poster is High quality and it has a nice shine, not too glossy but catches the light nicely.
The reason I say it is even better than advertised is the quality of the image. When I ordered it I thought it was just a blue background, which was cool, but when It got here I was surprised to find that some of the blue included features from surrounding states as well, with small borders and names that give it a nice touch and I prefer a lot more than just a mottled blue background.
I was hesitant to buy at first because it had few reviews, but I looked at the company store and it looked high quality and reputable so I bought it, and it lived up to its name. I don't know a ton about posters but maybe a little on the expensive side, but you get a good quality item in exchange.
I am giving it to my girlfriend to hang up and put some pins in after she got back from her trip to Cali, so I haven't seen it on the wall yet but I'm sure it'll look great, and it came with a nice set of recommendations and instructions for adding pins, coloring sections, etc. overall good buy!
