The poster is beautiful but, no matter the setting, even in a pitch black room without windows, none of the print was visible in the dark, though it is described as being "glow in the dark" with the use of the phosphorescent ink. I'll keep it because I like it well enough in daylight, and the quality of the print is high. I just wish I got what I paid for and what was described.
This is a great looking poster on heavy, high quality paper. And it glows in the dark - what else could you want?
Just a neat item - wish you all offered frames to go with the maps!
