I have fixed on the wall of my office, which is a gray tone, so everything goes very well together. I have placed V-2 photos in the left line of the V, a tip and a right, and it really gives very good, all my visitors appreciate.
A small regret: that is a little small (20 * 20) and suddenly it does not impress much as is often the case with photos of New York. Matter of taste and anyway by grouping them, like I did in V, it's really good.
