Spot the difference

This is Gnomad, he is quite the mysterious gnome. He has been a Regional Museums mascot since 2017 and he tends to get into some mischief! We are always trying to figure out his mysterious travels. We even believe that he is a time traveler to the days when Regional museums were very young, around 1925. Back then there were not as many items that we think are very common today like cell phones and computers. Below you will find a couple of photographs we found in our archives (old stuff). You may notice that the naturalist desk has been changed from one evening to the next morning! Since we have the benefit of these photos we are pretty sure that our good pal Gnomad had something to do with it. See if you can spot the difference! There are 9!
