In Droeshout portrait, how is the States discussed?
The portrait exists in two "states", or distinct versions of the image, printed from the same plate by Droeshout himself. Examples of the first state are very rare, existing in only four copies. These were probably test printings, created so that the engraver could see whether some alterations needed to be made. The overwhelming majority of surviving copies of the First Folio use the second state, which has heavier shadows and other minor differences, notably in the jawline and the moustache.
Later copies of the second state, with minor retouching, were also printed from the plate by Thomas Cotes in 1632, for Robert Allot's Second Folio, a new edition of the collected plays. It was also reused in later folios, although by then the plate was beginning to wear out and was heavily re-engraved. The original plate was still being used up to the Fourth Folio of 1685 (heavily retouched)  and then disappears. Already in 1640 William Marshall had copied and adapted the design on a new plate for John Benson's edition of Shakespeare's sonnets. All subsequent engraved reprintings of the portrait were made by later engravers copying the original printed image.
