In 1951, Cavanaugh won a National Sculpture Society Purchase Prize, giving him a lift to have his artistry recognized.
[1] In 1956 he left his wife and son, and other family, to move to New York City to pursue his sculpture career and make his way.
At the same time, Cavanaugh was receiving income from his twice-yearly exhibitions in his Washington studio space" on Swann Street, NW.
[5] Cavanaugh was prolific and sold numerous sculptures and other works from his Swann Street studio shows.
The breadth of Cavanaugh's work extended into less traditional formats including Flux Box Year Two (1967), one of many compilations of small artists' objects produced by the interdisciplinary movement, Fluxus.
