Ordeman, John T. "Frank W. Benson's etchings, drypoints and lithographs, an illustrated and descriptive catalogue." Hickok-Bockus, 1994, Summit, New Jersey.
Notes (object):
Stone lithograph. Fifteen prints of "Blue Herons" are listed as having been sold according to the artist's business records, and two are owned by Benson family members, although, as with all of his lithographs but the first, an edition of fifty was planned. Apparently each copy was signed by the artist, who presumably also printed this lithograph.
