I had bought Volume II of the current offering awhile ago. It was good enough that I ordered Volume 1, and it is even better. Among highlights are the Boeing 307. The book is offered by a place called Air Age, which seems to be a subsidiary of Carstens publications, that publishes several model magazines.
I think both volumes are great resources. I have a couple of other Matt anthologies and most of the subjects in these volumes are new- that is not the same as in the other anthologies (a couple are, but only a couple).
These drawing sets are three views with sometimes a few detail perspective views. No photos, just the drawings. Various scales, depending on size of subject, but scale always noted, and generally one of the architectural scales (1:32, 1:48, 1:96, etc).
Usually color scheme indicated, markings shown.
The titles are Paul Matt Aircraft Drawings, Volume (I or II).
