The stamp identifies the set as vintage Otagiri Original ceramics.
The Otagiri company operated out of Japan, producing high-quality handcrafted kitchenware and giftware.
Most of these specific animal-on-nest sets were manufactured and imported during the 1970s and 1980s. Having both matching bird shakers alongside the original ceramic nest base significantly elevates the value toward the higher end of the spectrum ($25.00+).
