"1 phototype by Gutekunst, 1 heliotype by Heliotype Printing Co., 2 Artotypes by Bierstadt, 21 Photo-typos by Britton & Rey, S.F., 4 half-tones by Moss Engraving Co., 4 half-tones by Heliotype Printing Co., 3 unidentified half-tones...contains an unusual gallery of the works by the major collotype printing houses in the 1880s. The early half-tones by Moss as well as the surprising ones by the Heliotype Printing Company add considerably to the allure of this publication. It was issued again [1888], but with all of the collotypes by Britton & Rey, whose abilities were not as high as the other companies."--Hanson Collection catalog, p. 87
