The sticker identifies the company as OLZ Glaskunst Zwiesel, which translates to "OLZ Glass Art Zwiesel." Zwiesel is a town in Bavaria, Germany, known for its glassmaking tradition, which dates back to the 15th century. The region is recognized for its high-quality crystal glass and decorative art pieces, supported by a longstanding history of craftsmanship. During the mid-20th century, around 1959 when this piece was made, Zwiesel?s glassmakers produced a range of custom and commemorative items. Local companies often collaborated with organizations and institutions to craft unique designs for anniversaries, events, or other milestones. This context situates the item within a broader tradition of bespoke glass production in the region. Shipping Policy Due to ever increasing postage costs, shipping is charged separately rather than hidden in the item's price. This method is more equitable, allowing customers closer in proximity to benefit from reduced shipping costs. For orders with multiple items, I'm happy to offer combined shipping (which can further save on shipping expenses). Returns are accepted, provided the item is returned in the same condition it was received.
