I discovered Pete Beard's "Unsung Heroes of Illustration" videos a few months back and will visit it from time to time.
I found myself watching this channel this morning and it was a lovely balm for an otherwise stressful day.
It occurred to me that if there was ever an audience who should know about this channel it was anyone who has subscribed to SVS! The creator has a very mellow british accent and the artwork is straight up inspirational.
You'll find artists that you didn't know you loved, and possibly discover a historical connection to the artists that you already love.
Please post other resources like this that you've discovered.
