Swimmy was first published in New York by Pantheon in 1963. The first British edition is Dennis Dobson, London, 1966, a picture book of 30 pages at 29 cm; both the British National Bibliography and Open Library note that it was originally published by Pantheon in 1963. It predates ISBNs, so identify it by the Dobson imprint and the 1966 date. American Pantheon copies are sometimes offered in Britain but are not the British edition.
We have not yet confirmed the issue points that tell this first impression from later ones. Until we do, compare your copy's title page and copyright page with the publisher, place and year above: any later printing or edition statement means it is not this one.
