publisher's decorated wrappers
Cover wrappers, generally decorated with a
woodcut, and usually produced on the same paper as
the text. These covers appear to have been issued
by the publisher as a means of making unbound
books more attractive to the customer, and were
intended simply to advertise the book, not to
serve as a permanent or usable binding. As such,
they seem to have been an experiment by several
competitive Augsburg printers, the earliest
examples being issued by Schonsperger in 1482. (347 )
