Ferryman has kindly sent in this close-up of the A logo below, which appears on the side of his amazing T in a Circle Space Vehicle - above - posted earlier on October.
Below is the official 1960's PRJECT APOLLO insignia and it's clearly the basis for the A logo on the space toy.
According to NASA the Project Apollo insignia was a disk circumscribed by a band displaying the words “Apollo” and “NASA.” The center disk bore a large letter “A” with the constellation Orion positioned so that its three central stars formed the bar of the letter. To the right was the Earth, with the Moon in the upper left of the center disc. The Moon’s face represented the mythical god Apollo. A double trajectory passed behind both spheres and through the central stars.
Are there more toys with this insignia?
