And another landmark store bites the dust. Morris Brothers, the sportswear purveyor on 84th Street and Broadway, which has been selling the required T-shirts, tube socks, and name tapes to campgoing youngsters on the Upper West Side for the past six decades, unveiled new window displays this week and they're not pretty. Banners proclaiming final sales because of their imminent departure from the neighborhood were unfurled. According to local buzz, the rent for the 5,000-square-foot space has more than doubled, sending the owners packing. No word yet on what'll set up shop there once the sale ends in July, but we'd be happy to start a pool: bank branch, Starbucks, or nail salon? Heck, it's a big enough space, maybe all three! —S.
