I will be in Europe for a few weeks in May and would be happy to show 
UltraStable prints to those who wish to see them.  My schedule looks
like this:   London, May 1 -7; Paris 8 - 15, and Amsterdam 16- 20. 
If you will be in any of these places at those times, please let me know
and we can arrange a meeting.
