I had an original MM (& 2 Superiors) with original white piping myself [especially more common on Combination Ambulance-Hearses] so, I would question that observation. The door panel fleur de' lis ? design ....another subject. A worthy 'keeper' for MLK and historic collectors but, I think more prudent to market it for less. Never had much luck on 'major personality cars' pulling that much more then the norm(Burt Reynolds,Dale Earnhardt etc). As far the drapes; my humble opinion; everyone has a different take on 'a peak of the coffin'. Hard to see on that old photo but, it 'looks' like they maybe were trying to match the position of the drapery on the photo at the airport?
Acknowledging it belongs to a fellow member; I respectfully suggest, lower your starting price...as we're in a major recession/ political year of uncertainty.
Hey, future bidding might prove me wrong!
