I’m uncertain whether the interest in label pins and their history belongs to phaleristics or not. Perhaps phaleristics proper only study symbolic items granted to someone by someone, and not to label pins that you purchase? Until somebody enlightens me on this scholarly obscurity, I will place socialist pins under the label “socialist phaleristics”.
Anyhow, the cause for this post is to draw attention to a very neat site about pins form the history of the German Social Democrats that I just stumbled into. Have I look at “Pins zu 150 Jahren SPD-Geschichte”!
This blog post is decorated with medallions/charms from the Knights of Labor as displayed in F. Irons & Charles A. Russell, Illustrated Catalogue of Solid Gold. Society Emblems, Pins, Buttons and Charms, Providence, Irons & Russell (1895) and a marvellous pin from CNT-FAI that I happend to find on e-bay.
