photos were to promote the new 1977 "ultra scheme" interior on the
727 and the conversion to all leather in both the 727 and 747. Even
though N601BN maintained its original "solid color" scheme. The
leather came from Argentina. Payment in lieu of cash from that country.
That is why Braniff made everything from coasters to business card
holders to seat covers in this Argentinian Leather.
These were given out in press kits to the media. Especially newspapers,
which usually only prints B&W photos.
