This picture is a line engraving of Dexter, produced around 1902 by the Department of the Treasury's Bureau of Engraving and Printing (BEP), as part of a BEP presentation album of the first 42 secretaries of the treasury. This engraving shows him wearing a dark coat over a frilled shirt and cravat, garments that were fashionable during his lifetime.Engraving credit: Bureau of Engraving and Printing; restored by Andrew Shiva
