Ron Finley MasterClass billboards...

With many people finding themselves homebound in recent months due to the global coronavirus pandemic, there's never been a better time to promote a self-education and improvement concept like MasterClass.

The streaming platform allows subscribers to watch or listen to hundreds of video life lessons from over 80 of the world's best professionals, like photographer Annie Leibovitz, chef Gordon Ramsey, fashion icon Anna Wintour, filmmaker Martin Scorsese, actress Natalie Portman and gardening from Ron Finley.

If the provocative language wasn't enough to make this billboard for the self-proclaimed "Gangster Gardener" stand out, then this neon embellishment certainly draws your eye even more at nighttime.

This billboard creative was first spotted westbound along the Sunset Strip on April 28, then rephotographed with the neon sign addition on May 13, 2020, at the same time as the standard eastbound billboard on the flip-side of this hoarding.

If there's a passion you've yet to explore, then maybe this service is for you. Expert advice and life experience are invaluable, and if you want to be the best you should learn from the best.
