I first found this site a few months back when researching the logo for Mitsui O.S.K. Lines (it appears on a shipping container at a construction site in my area): https://www.modernillustration.org/archive/mol1969ryoheiyana...

Semi-relatedly to the OP, I dug deeper and found that M.O.L. continues to regularly update their site in honor of the logo's illustrator (including fresh monthly wallpapers and printable stationery): https://www.mol.co.jp/en/yanagihara/

I was pleasantly surprised by the ongoing reverence they have for their illustrator's legacy.

very cool, thanks

If you enjoy the retro style of art, especially the cartoony stuff, I would recommend checking out the work of artist Derek Yaniger:
