Reads in part, "...The fuel chamber and its addition will feel the pressure of the gases...The tube where the products of the explosion will go spreading permanently and become colder because of transferring the hot temperature to kinetic [energy] which gives movement to the spaceship...Rough estimation lets us assume the speed of 30 meters a second...the weight will be three timers greater than the earth weight..." On the verso is what appears to be a hand-written table, giving speed measurements. Couple of minor pinholes. Some toning, o/w VG. $3,000-4,000
