We have tried to make all entries as helpful and at the same time as concise as possible. The book is arranged alphabetically by artists, with anonymous items in front, divided by country of origin. Where we have offered collections on a particular theme or books on any subject, they are listed on the last pages under "Collections and Books and Periodicals" (If the collection or book is by a single artist, look for it under that artist's name).

If you have a poster that you would like to sell, or simply establish what its value might be, or if you are offered one and are thinking of buying it, this guide can be of great value.
