Duveen and Klickstein are contradictory about the date of the first number, which was in fact Monday, February 20, 1786. They also state that the last issue of 1786 was number 134. In fact the last number issued in 1786 was no. 135, and it appeared on Dec. 29, 1786. If there were 18 numbers issued in 1787, the 1st would have been issued Jan. 1, 1787, and the 18th Feb. 9, 1787.
Each v. has collective t.p. and index.
Each v. has woodcut title vignette, head-pieces, tail-pieces.
