Books and bidders
(1927)
“ Block books are, of course, among the most desirable and the most difficult to obtain of all the treasures of the bibliophile. Even a single sheet torn from a block book is valuable. I recall vividly, when in England many years ago, my first visit to an old library which contained four perfect block books, all in magnificent condition. The margins were uncut and, in fact, they appeared to be exactly the same as when they left the hands of the unknown printer in the fifteenth century. ”
