[In justice to the fac-similist who has so faithfully copied the following designs from Blake’s works, the publisher would state they were made under somewhat difficult circumstances, the British Museum authorities not permitting tracing from the copies in their possession. In every case the exact peculiarities of the originals have been preserved. The colouring has been done by hand from the designs, tinted by the artist, and the three illustrations from “Jerusalem” have been reduced from the original in folio to octavo. The paper on which the fac-similes are given has been expressly made to resemble that used by Blake.]
