This is a highly refined art object made of Lucite (acrylic optical resin), born during the heyday of mid-century modernism in 1960s America. Inside the thick, transparent Lucite, genuine American coins (cents, nickels, quarters) are encased, with a three-dimensional glass hourglass motif at the center. More than just a decorative item, it's a conceptual art piece that encapsulates "time (hourglass)" and "value (coins)" simultaneously, reflecting 1960s America. It was originally made for the high-end desk accessory/art glass market of the time. The structure, where the coins appear to float and the hourglass seems suspended in mid-air depending on how the light hits it, is a testament to craftsmanship and material quality that cannot be replicated in modern mass-produced items. The size is approximately 10cm x 4.5cm in height, weighing about 460g. It's incredibly substantial and has a presence that elevates the space simply by placing it on a desk, in a study, or on a gallery shelf. This is a typical mid-century Lucite piece from the 1960s-70s, and it's a genre that is now traded as a collector's item in the overseas art glass and design object market. It's a type that rarely circulates in Japan, and it's an art object that "those in the know will recognize at a glance." --- ■ Specifications ・Era: 1970s (estimated) ・Material: Lucite (acrylic optical resin) + glass ・Interior: Coins + glass hourglass motif ・Size: Approximately 10cm x 4.5cm ・Weight: Approximately 460g --- ■ Recommended for: ・Those who love mid-century design ・Those who like US vintage, Eames, and Knoll styles ・Those who want to place a "meaningful object" on their desk or in their study ・Collectors who seek both artistry and asset value Refer to the fifth photo from the bottom; there is a slight scratch.
