Original vintage magazine ad, PHOENIX METAL CAP COMPANY of Chicago, IL. and Brooklyn, NY.   Oldest and largest among the living things on earth is the General Sherman, majestic forest giant of the Sequoia National Park.  Native only to the United States, it is tops in the world of living things.  The Phoenix Compo Cap is not the oldest metal closure - the screw cap antedates its invention by a number of years - but it was the first truly commercial closure to be manufactured in this country.  Nor is the Phoenix Compo Cap the largest in sales - for it is strictly a quality closure for quality products - but it is tops among metal caps for glass containers.  Old 1938 glass industry advertisement. Would look fantastic matted and framed.

Approximate size 8 x 11 inches.
