John Speed proof maps - Atlas.2.61.1
Cambridge University Library has one of five known sets of proof maps prepared for John Speed's Theatre of the Empire of Great Britaine, 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 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 following the death of Rogers in 1604.
Below are the high quality scans of all 66 of the proof maps (requires Adobe Flash Player).
Full-size printed copies can be purchased online here. Or if you have a Cambridge University Library Card you can order a copy in person at Imaging Services and save VAT and postage and packing (although you will have to return to collect it).
The Press Release provides more background information about the atlas as does the article on pages 8-9 of the April/Map 2011 issue of the University's Newsletter.
