Compare the two title pages of Titus Andronicus that are shown here. When Philips purchased the first title page, bound separately from the full quarto, he evidently believed it to be genuine. However, later analysis shows that Philips was duped: it is, in fact, a hand-drawn copy. The value of even a title page of a Shakespeare quarto is astronomical, clearly tempting a late 19th or early 20th century forger. It is also possible that an acknowledged facsimile was repurposed into the real thing by an unscrupulous dealer or owner at some point in its history. The second title page is an 'authentic' fake: it is acknowledged as a reproduction in a handwritten note within the book itself.
