Seen on eBay, two Apple LaserDiscs.
The first one (sold for $135) dates back to 1989 and appears to be a sort of visual manual, spanning both sides (so a maximum of 60 or 120 minutes). The title? Introduction to Desktop Publishing & Presentations.
The second one sold for the same price but is different: Macintosh Fundamentals 2.0. This one also has two sides, with no indication of the encoding format.
