I thought some of you who collect German stamps might want to have a look at this site. They show most but not all German stamps with lots of information. It´s in German but easy to use.

On the start side, click on Deutschland on the right side. Choose a category. When you have chosen your category you can click on Detailansicht for more info. Deutsches Reich is my favorite.http://www.philadb.com/?site=
