Blackhawk Unpublished: Chaykin?

I have no idea who drew these pages, so if you know please feel free to let me know.

I do have a thought however, while reading "Comic Book Implosion" by Keith Dallas and Joh Wells there is an interesting tidbit on page 102.

There is a description of a Blackhawk Trilogy by Len Wein and Howard Chaykin which was supposed to be published in the 70s version of Men of War.

However it became another victim of the great 1978 DC Implosion. p> Could these possibly be these unpublished pages?

I cannot believe DC would let a Chaykin book go unpublished.

But then I would never have imagined DC would let a Carmine Infantino Blackhawk series go unpublished.
