Please send a close-up of the stamp that I see on the bottom of shelf where drawer goes and a view of the backside.
Yes, and thank you for your patience, I had to leave my office shortly before I received your images earlier.
The stamp is from the Douglas Plywood Sales Co which was in business from 1960 - 1979. Thus, your hanging spice cabinet dates to 1960 at the latest.
It was likely made by a hobbyist home or shop class woodmaker.
