A recent acquisition from ebay was a pretty good B&W glossy showing a Martin Company illustration of the Titan IIIC launch vehicle, circa August, 1964. One of the better Titan IIIC illustrations I’ve seen, showing the innards to good effect.
I have uploaded the full 600-dpi scan to the 2017-11 APR Extras Dropbox available to all $4 and up APR Patreon patrons. It’s in two formats… the raw scan, and a cleaned-up version that looks better. Also included is the press release printed on the back of the glossy. If you are interested, take a look at the APR Patreon and consider signing up.
