New York-based art appraiser David Shapiro talks about: What he does as an appraiser, whether in-person inspections or putting together reports using photographs at the computer; his involvement with the Detroit Institute of Art’s collection appraisal, which was connected to the largest municipal bankruptcy in the history of the country; how appraisers value a work of art, from auction records to gallery sales (to the extent that can be verified) to the market as a whole, including trends; turning down offers to appraise works that have no apparent market value; his own career as an artist prior to becoming an appraiser, which included having success selling his work before he was even out of high school; how, when he returned to making art after grad school in art history he had less success, learning about “the fickleness and vicissitudes of the art world,” as he put it; and how he appraises emerging art, including within a market with a lot of movement in values, both up and down.
