Isenbeck Beer Crown Cap

This is a vintage metal crown cork bottle cap from the German brewery Isenbeck. The cap features a striking three-color lithographed design: a deep cerulean blue outer ring bordering a golden-yellow central disc. At the heart of the design is the heraldic Isenbeck emblem, which depicts a black double-headed imperial-style eagle with outstretched wings. On the breast of the eagle is a small white shield containing the interlocking letters 'CB', signifying the brewery's historic roots. Physically, the cap displays the standard 21-tooth fluted edge common to late 20th-century glass bottle closures. The condition appears relatively good for a used item; there is a slight deformation on the fluted edges and minor chipping of the blue paint consistent with mechanical removal by a bottle opener. No significant rust is visible on the top surface. The style of the logo suggests a manufacturing period between the late 1960s and 1980s. The lithography remains vibrant, indicating the item was likely kept in a dry environment away from direct sunlight, preserving the integrity of the graphic branding which is highly valued by breweriana collectors.
