Antarctic Item 005

Similar as this Bud can appears to the previous post, this one proves older on close inspection. In addition to having lost its red pigment, this one's blue has faded too. Oxidation is more advanced here, particularly on the top and bottom. But the biggest clue is the fully-detachable pull-tab which was phased out in the 1970s. This can's tab, regretfully, remains somewhere in Antarctica.
