Finished in 1972 by renowned artist Arnold Belkin, a mural created at a Manhattan playground in his trademark Mexican-influenced style but has been deteriorating slowly over the decades. There has been little impetus to preserve it until now. Residents are clamoring to have what may be the artist’s only outdoor U.S. work restored. It may happen, thanks in part to Heritage preservation, a Washington D.C.-based national organization devoted to preserving the country’s cultural artifacts. It would not be the first time the organization has restored a mural in New York City: In 2009, it completed repairs to Eva Cockroft’s 1986 work “Homage to Seurat: La Grande Jatte in Harlem” (pictured) with money from a preservation foundation. Shouldn’t Sondheim have contributed, too?
