In 1954, physician Lawrence Gwyn Van Loon donated this map to the Albany Institute of History & Art. At the time, it was reported in The Knickerbocker News that the map was a rare engraving by Albany silversmith and engraver Koenraedt Ten Eyck. The initials "KTE" engraved in the bottom right seemed to confirm that attribution. The map depicts the community of Albany as it would have appeared at the beginning of the eighteenth century. Years later, historian Charles Gehring of the New Netherland Institute documented that Van Loon forged many documents in the 1930s that he later passed along as authentic.

This map is now known to be one of Van Loon's forgeries.
