Donations and Swaps

As a collector of Air Sickness Bags. I am interested in obtaining new specimens. If you happen to encounter any kind of sickness bag, would you kindly send me one (unless it's plain white)? Here's the "corporate" address:

Steve Silberberg
9 Third St.
Hull, MA 02045
USA

Actually, airlines change their bags every few years, so if you ever notice a change, please snatch that bag and send it to me! I would be very grateful for any help you might provide. Many thanks in advance.
