Co-Curators of New Hampshire Art Association and League of New Hampshire Craftsmen: A Retrospective Richard Candee and Robert Chase discuss The Grace Casey Years and the boom in state and local support for the arts in New Hampshire. With the ?revival? of historic Portsmouth in the mid-1960s Grace Casey and Miriam Sawyer sold work by NHAA artists in the River House Gallery on Bow Street. Casey soon established a branch Art Association gallery in the Wentworth House at Strawbery Banke and helped established the Prescott Park Arts Festival.
