Eagleson & Co.

Eagleson & Co. was in business in both San Francisco and Los Angeles. This shirt button hook was likely given away at both locations since it is without a city embossed upon it.

And from the Langley's SFCD from 1886 -

Sommer & Kaufmann San Francisco

This is the older 1890s style fancy hook. Although this is a duplicate, it is in fine condition and the price was right.
