Hi again Aimee, I can't say that we've ever notice anything specifically aimed at Tirtoff's work, but if aty is your thing, you'll never want to leave St. Petersburg.
From the Winter Palace's Hermitage museum, through Catherine's Palace, to the Marble Palace and Peter & Paul fortress, the collections of art & history are stunning.
But for something quite stunning, try to take a trip on the metro rail system, you'll need to check which ones, but some of the stops are decorated more highly than many of the worlds Palaces & Stately homes. Again search the web for some photo's, they're amazing.
Hope this whet's the appetite,
Alan & Katrina
