Many early collaborations between talented and now celebrated artists have been forgotten in the mists of time. It would be interesting to do a kind of cultural archaeology to rediscover such events.
For example, the Academy Award winning animator John Canemaker and the Academy Award winning actor Joel Grey collaborated more than half a century ago. I’m guessing that very few people remember that.
If you can figure out what they collaborated on, you get extra points. 🙂
