Kona coffee packages from the 1950's

The back of the Caswell tin in the middle reads: "THIS COFFEE possesses surprising drinking merit, uniform quality, and natural strength, appealing at once to the epicurean taste and the lover of real good Coffee. TO INSURE its retaining all of its good qualities it is never sold in bulk, but taken fresh from the roaster and packaged in sealed cans, reaching the consumer with not a vestige of its strength gone. Packed Exclusively by Geo.W. Caswell Co., San Francisco, California"
