A rare set of all original 13 vintage Penguin Guides with red covers (G1 - G13) - all 1st edition. The condition of all the books is good and extremely good for the four with dustjackets.  Some have the signature of former owners, but the text is clean and there is very little evidence of foxing.
Also included in the package are G14 and G15 from the later Penguin Guides New Series.  Although described as "New Series" they are officially a continuation of the same set.
