I am an art history professor in Western NY state and I started collecting floating pens a few years ago. They are the plastic pens that when tilted move a boat, plane, etc. Most are made by the Eskesen company in Denmark. The collection started out as a momento from museums and historic sites but I have become fascinated with the various designs. The best pens I have are from museums. If this type of pen is available in your museum shop please e mail me (and if possible give me the address of your museum so I can order some?) or if you know of museums that have them please let me know. I would also like to give these to students in my art history classes as prizes for "Jeopardy" games played! Thank you! Nancy Knechtel
