Bears
In SYWTBAW, in the midst of the description of the many statues given the semblance of life by Kit's use of the Mason's Word, some "bears" are mentioned. These are almost certainly the bears that stand atop the southernmost of the pedestals flanking the gate of the William Church Osborn Memorial Playground at Fifth Avenue and 85th Street.
The bears are small bronze figures cast by the artist and sculptor Paul Manship in 1955. The pedestals were designed around the same time by architect Aymar Embury II.
A side note: William Church Osborn served the city as president of the Children's Aid Society, as president of the Metropolitan Museum of Art, and (maybe most memorably) as the president of the New York Society for the Relief of the Ruptured and Orphaned. (SYWTBAW)
