Currently reading 'Shrouds of the Night' by David L Block and Kenneth Freeman. This has reproduced some drawings by Trouvelot and a reference to the book 'The Trouvelot Astronomical Drawing Manual'.

I found an online version of the text but it does not have the plates which are described in the book. Does anyone know if the plates are available somewhere?
