The following showreel provides covers work from pre-1990. As an overview of the work from this period, it provides some indication of the breadth of Charlton’s sculptural work. The images have been digitized from slides.  For further documentation please contact the artist.
Charlton spent much of the 1980s in the United States of America. Initially based in Upstate New York completing graduate work he exhibited extensively in regional exhibitions and briefly showed with John Gibson Galleries before moving to New Hampshire to take up a lecturing position at the University of New Hampshire.
During this time he exhibited across the US and was represented by Akin Gallery in Boston. Much of the work represented here stems from this prolific period. In 1991 Charlton returned to New Zealand.
