I had a copy of the 1970 "Model Rocketry Manual." In fact, I still have it, less covers and several pages. It had a black cover with an line illustration of a rocket . . . in red, I believe.

It was definitely an MPC co-production. Most of the models shown were MPC kits, and their were subtle plugs in the text for the company.

I saw the later edition in Powells a few years back. I should have bought it, for the collector's value.
