The Clark Museum in Williamstown Mass. is hosting a Pissarro exhibition through October 2nd...and sadly I won't see it, because I am not speaking there on my Monet novel until October 9th. I love Pissarro with all my heart! If someone does go, please do leave a comment here. Here is the url for the museum: CLARK MUSEUM. And let me once more recommend Pissarro's Letters to his Son Lucien.
