A nice copy of the tenth book in the series.   This is the 1946B-28 printing according to H&HI, Eighth Edition.  The dust jacket is overall in VG- condition, with some typical minor chipping at the top and bottom of the spine, but the spine colors are uniformly faded from the book having spent too much time on a shelf exposed to the sun  ( see picture 4 ).   The book is VG+, with slight wear to the top and bottom of the spine.  The internals are completely unmarked.   A nice, tight, square, clean copy of this book.
