Hello "luv2cruisedisney" and "martincorral":
It is a "Shadow Box" that I made using a 16x20-inch frame, the frame I bought at Costco, and I placed the frame in such a way that could open as a display, so I can easly clean and arrange the pins. The background image constructed by scanning the paperwork that I got during the trip and put them in a "photshop" file and I made the final print on paper using a 16x20 inches high-quality photo paper. The photo in the center is the original picture that we bought on the boat.
The final print was not placed directly on the wooden box of "Shadow Box", was placed on a base made of layers of styrofoam and cork, as seen in the photo. Then everything was stuck inside the box Shadow.
If you wish, I can gladly send you a high quality JPG file of background I did.
