Published in 1992 by Harper Collins.
This is a fun book about an old lady who buys some lawn flamingos to brighten up her urban view. She puts them on her fire escape, but the fire inspector tells her she can't keep them there, so she moves them to a neighboring roof. She loves them so much she buys more so that they cover the entire roof. She is startled when she sees a wrecking ball plummeting towards the building where her flamingos are, but then magically they start to fly away.
Apparently this is the author's only children's book. He is currently a professor at Kutztown University in PA where he teaches illustration and graphic design.
