Poster sample. This photograph of Niels Bohr appears in my Photographic Periodic Table Poster representing bohrium, which is named after him. This highly unstable element can't reasonably be photographed, and a picture of its namesake seemed like a reasonable alternative. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of. This photo is courtesy the Niels Bohr Archive, used with permission.

Sample from the Everest Set. Up until the early 1990's a company in Russia sold a periodic table collection with element samples. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. The samples (except gasses) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid. Radioactive elements like this one are represented in this particular set by a non-radioactive dummy powder, which doesn't look anything like the real element. (In this case a sample of the pure element isn't really practical anyway since the element exists as a short-lived laboratory curiosity only.) Since this set was made before 1997, they haven't even printed a name on the ampule: This element had not yet been named. To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one, or you can see photographs of all the samples from the set displayed on my website in a periodic table layout or with bigger pictures in numerical order.
