I, too, love the old Pan American scheme. Actually, most schemes of the 1960s looked good on the 707; particularly noteworthy are:
TWA (double globes)
Ethiopian (this scheme looks good on anything that flies)
Unfortunately, most of these liveries were replaced with much less dignified ones in the 1970s.
