If you have never heard the name Bob Fujitani, you are in for a real treat. As far as Golden Age greats go, he may be the most ‘under the radar’ of them all.
His work is as prolific as it is exquisite, but his name rarely seems to come up in conversations about the all-time greats.

Born in Bob Fujitani was of Irish/Japanese descent and attended New York City’s American School of Design.
He started work in comics shortly after America’s entry into World War Two.
