There is a large exhibition of the work of Isaac Levitan on at the moment in Saint Petersburg to commemorate the 150th anniversary of his birth. Unfortunately I wont be seeing it as it closes tomorrow. I did manage, however, to pick up the catalog directly from the printer. There are a lot of paintings I had never seen published before and overall the reproductions are quite good, even if the catalog itself is rather petite.
Anyways, if you’re interested, you can contact the printer directly here. It was €38 with shipping to Italy.
