1904: Two different types of handwriting; the first attributed to Artus Van Briggle, prior to his death on 7-4-1904; the second, attributed to Anne Van Briggle, with the distinctive V & A in Van Briggle. 1904 pieces have markings of inscribed Double-A, Van Briggle, date of 1904 and Roman Numeral V for clay type; with an impressed Design #.#146 “Early” 1904 #146 “Later” 1904 Robert Wyman Newton notes change in script style; particularly the V & A in Van Briggle.1905: Robert Wyman Newton shows 5 versions of markings for these pieces.All have inscribed Double-A, Van Briggle, 1905; as well as impressed Design #.
Spgs., 1906 (it is a 0, not a 1 in real life) and Design #534 all incised.#335D “XV” on bottom, as opposed to “VX” as stated by Robert Wyman Newton. In Catalogue of Van Briggle Designs, #355A referred to the matching pitcher; #355B to the mugs. It also resembles #434, which was the first design created in 1906. Human error might be responsible for someone dating it 1905 early in 1906, like many of us forget when writing our first check of the New Year! 1906: Newton writes that by 1906, (1) Roman Numerals indicating clay type no longer appear, (2) Design # is now either inscribed or impressed, (3) “Colorado Springs” or “Colo.Spgs.” is sometimes added underneath “Van Briggle.” Also, at some point in 1906 and throughout part of 1907; the clay used, was what I call “chocolate clay” very much the color of a Hershey chocolate bar.#201 with incised Double-A, Van Briggle, date of 1903 and Roman Numeral III for clay type, in the handwriting attributed to Artus Van Briggle; and incised Design #201.#192 with all the typical 1903 markings, plus the addition of black mark Roman Numeral indicative of experimental markings.
