I bought this puzzle as an activity for my girlfriend and myself. It took us about 5 days to complete it, and we had a total blast during the whole process. It was challenging and fun at the same time; and when we finished we felt completely rewarded by the beautiful result. A definite must for any puzzle lover. Oh and the coolest part is that when you have finished it, you can glue it together, frame or mount it, and watch it GLOW IN THE DARK!! woooooooohoooooooooooo!!!
