Alas, the Philadelphia Museum of Art and its associated sites (Rodin, Perelman Annex) are not open on Mondays. (Unless the Monday is one of certain holidays -- go figure!) It appears the Barnes Foundation may be open every day; advance tickets are recommended.
The stuff on the 2nd & 3rd I doubt I can make, it's the weekend of mounting an art show in which I'm deeply entangled, but with a little luck, I might at least get to see your exhibit. It is amazing how much art-related stuff is trying to happen in the next month or so.
Hope it all goes well.
