“Children are tough, though we tend to think of them as fragile,” Maurice Sendak once said. “They have to be tough. Childhood is not easy.” Making it a little easier was Sendak himself, who expanded imagination’s map to include night kitchens where boys might be baked into cakes and islands where unruly Wild Things hold wild rumpuses. The late author is celebrated tonight at 92Y Tribeca by children’s book historian Leonard S. Marcus, artist Rick Meyerowitz, and others. Farther uptown, the Society of Illustrators is exhibiting hundreds of original Sendak illustrations. Exhibit through August 17, Society of 
Illustrators, 128 East 63rd Street,

Mondays-Sundays, 7 p.m. Starts: July 16. Continues through Aug. 17, 2013
