I came across one of the more unique sets of 35mm slides I've seen on eBay in some time. They purport to be from a 1960s animated business presentation film called "Who Profits from Profits?" No other information is provided, and a quick internet search for the film yielded no results. What I can confirm is that these are in fact some of the niftiest bits of vintage animation you'll see today. Even business films, with their admittedly short shelf life, were animated with more care than most commercial or entertainment productions today. If anyone has any information on this film please let let me know, I'd love to see it.
