Did you catch Mayor Tom Menino on “Antiques Roadshow” the other night? The episode that was taped last summer finally aired, and there’s a little follow-up. Menino, you’ll recall, brought in a painting — a landscape of a sleepy Vermont town nestled in snow — that had been hanging for years on a wall at Boston’s historic Parkman House, and it was appraised by Colleene Fesko at $50,000. At the taping, Menino said he had no plans to sell the painting, but he would get it insured. Tuesday, a spokesperson for the mayor told us that Hizzoner, who’s a big fan of the PBS show, did, in fact, get the painting insured and it’s now back on the wall at the Parkman House.
