Pioneer 10 flew by Jupiter in December 1973 and Pioneer 11, in a more polar trajectory, one year later. We present some of the pictures of Jupiter made with the spin-scan technique by the imaging photopolarimeter. The pictures are presented here without comment as a detailed description of Jupiter together with references concerning the instrument and its results, and were published in the book, Jupiter, edited by T. Gehrels (University of Arizona Press, 1976).
