Thanks to you who have responded. I am still on a pen quest. I am looking for museums and historic sites that sell souvenir pens - the pens that when tilted have a boat or object that slides back and forth. If you have seen these pens somewhere - please tell me where! If you have them in your museum gift shop - please let me know! I have found pens from the museum list so far at: Fort Steele Heritage Museum Seattle Art Museum Cliff House in San Francisco Parthenon in Nashville Weisman Art Museum at the University of Minnesota among other sites What a great variety! Thank you!
