This is an American antique grandfather clock. It was made by the Herschede Hall Clock Company in 1915. This clock was made especially for the exposition at the Panama Pacific International Exhibition of 1915.
The clock strikes “Bim Bam” on the quarters and strikes the hour on two tubes. The silvered brass dial has blued steel hands and features an early night sky moon dial. The case is cherry with an interesting carving on the lower panel.
