Unless Kodak were doing a field trial to check out the re-introduction of Kodachrome sheet. Not impossible, there was a field trial by at least one lab in the UK maybe 10 years ago of a Kodak colour RA4 paper on fibre-base, (which was not adopted, needless to say.)

That's a shame IMO, Martin - FB would give a new dimension to colour printing. I have many old colour FB prints in the family archives and I think they're much nicer than plastic prints of today. Washing prints would've been a real chore though :-) All IMO, of course.

PE, the Kotavachrome you mentioned would have been interesting too, but I think Kodachrome's tendency to fade in sunlight would have been a real liability unless it was dealt with. Again, all IMO.
