The picture shows one of the largest vaseline glass in the country. The glass gets its characteristic yellow-green color from uranium oxide, and, as a consequence, is mildly radioactive. What better way to tell your loved ones how much you esteem them than to give the gift that emits alpha particles for years and years? And such a topical gift as well! Especially thoughtful if the recipient owns his or her own geiger counter.
Update: Neatorama posted a very similar item the same day I did. I swear I didn't steal the idea!
