I must confess I was a little confused already during the delivery. We got quite a big mailer in which ultimately only three arches were in postcard size. The install was easy at the "larger" parts such as the moon, shooting stars, etc., most of the other Stars are so small that they hardly gets heal from the film. Very unfortunate. Have me a little larger presented. The luminosity contrast is great. We radiate most evenings for a few minutes at so that they light up the night. Nevertheless, I would look for another product the next time.
