What are these Chinese character stamps? I found these stamps in an old book, what are they I can hardly make them out? And what do they mean.
The stamp in the first picture says


  郭顯德


It is a person's name, and if you prefer simplified Chinese, it would be


  郭显德


The stamp in the second picture says


  烟台 · 長老傳道會


The first two characters is the name of a city in Shandong province, while the rest is the name of a club.
