Charles Waller's illustrations, paintings, and assemblages combined whimsy, wit, and humor with sarcasm and social commentary. His work — paintings on distressed tin, embellished bone, layered and textured collage and constructions using vintage objects of iron and wood — appealed to a wide audience and reflected his unique take on life. Mr. Waller died at home in Springs on Jan. 16. He was 66 and had contracted Covid-19 two weeks earlier.
