Dugald Stermer was art director for the left-leaning Ramparts magazine during the late 60s and came across Cuban posters when Reese Erlich, a reporter on the magazine returned from Cuba with a collection that he had acquired. Following this discovery Dugald put together a subsequent collection and produced this classic book on Cuban posters using his own text covering details of the agencies that were producing posters in Cuba. Susan Sontag also contributed text offering her views on poster production (which differ from mine in many ways).
The book itself is the best record of Cuban posters. It is a very large book and all the images are full colour reproductions covering a single page each. I guess this is the result of Dugald's influence. As a passionate and enthusiastic art director he must have been keen to preserve them in as big a format as possible. When I asked Dugald what happened to the posters they used for the book he told me they were left behind at the publishers, where they may have ended up in the bin.
If you collect Cuban posters this book is essential.
