Bookpile bookplate of John Marlar? (18th cent.)

An example of a distinctive 18th century style of bookplate, the 'bookpile' bookplate, bearing a monogram of the initals J.M., and possibly belonging to John Marlar, who had a similar bookplate made for himself bearing his full name and his residence, Mitcham Common in Surrey. For further details see Brian North Lee's Bookpile bookplates (1992). The bookplate appears on two volumes of incunabula in the Library, both from different sources, one of which is a copy of Caxton's printing of the English translation of Cicero's De senectute of 1481, the Library's oldest English printed book.
