Over the past few years I had the opportunity to view a number of fantastic
"travelling" exhibits of truly great works of art, some of which is rarely
seen by the public and never regretted having to travel from Montreal to such
places as Washington, Boston, Toronto or New York to view  them.
 
Some of these are well publicized (accross the US and Canada) others
do not seem to get into the media.
 
I do not know if this is the right forum, but it could be of interest if such
events were posted in a newsgroup.
