After Bonner's death in 1726, his partner William Price assumed sole ownership of the Boston plan, which he reissued several times over the next 40 years. Facing competition from William Burgis' attractive plan, Price made numerous changes, notably the addition of a decorative cartouche. He also added numerous streets in the south and west and along Boston Neck, with buildings shown by shading rather than perspective view. The re-engraving was done by Thomas Johnston, who had also engraved Burgis' plan. The result is overcrowded and even overwhelming, but the map remains the best visual record of pre-Revolutionary Boston.
