TURNER, RALPH. B.1935.
High relief of Alphonsus Peak, made at the Lunar and Planetary Laboratory, Tucson, AZ, April, 1966, reinforced greenish-gray epoxy, 1280 x 1220 mm, inscribed at top "Scale 1:20,500" and "West," and at foot "April 1966 L.P.L. | Alphonsus Peak | R. Turner," framed. Together with a large group of photographs used by Turner in the preparation of the relief.
A VERY LARGE AND STRIKING RELIEF OF ONE OF THE MOON'S MOST NOTABLE FEATURES. Turner's model of Alphonsus Peak was initially done in plasticene over six months, before a cast was made in epoxy. Kuiper and his team were particularly interested in the rille that passes by the peak at the center of Alphonsus Crater, and appears connected to the crater at the lower right of this relief.
Photographs from Ranger IX, which impacted the Moon on March 24, 1965, were the primary source for this relief. Included in the present lot are approximately 70 gelatin silver prints (20 x 16 inches and smaller) of Ranger and Lunar Orbiter photographs, mounted on board and frequently captioned below by Turner, sometimes explaining that they were used for "shadow determination."
