Cambridge University Library has one of five known sets of proof maps prepared for John Speed's Theatre of the Empire of Great Britaine (Atlas.2.61.1), which was published in 1611/12.
The maps were printed from copper plates which had been engraved, in reverse, by Jodocus Hondius in his workshop in Amsterdam. Maps printed from the plates - proofs - would have been sent back to England for checking.
The maps in Cambridge University Library's set of proofs - known as the Gardner copy after Dr Eric Gardner (1877-1951) the former owner - are in a late state of preparation, but many were altered before being published. The map of Cheshire, which had been produced as early as 1603 by English engraver William Rogers, was completely replaced for publication and only two copies of the proof map of Cheshire are known to exist.
None of these proof maps have text on the reverse. (The text on the reverse of published maps can sometimes be used to narrow the date of publication since the text was sometimes reset between editions).
All 66 maps are now viewable in the Cambridge Digital Library

The original maps measure approximately 40 x 53 cm (16 x 20.5 inches ; = A2 or 2 x A3).
