Pen Nibs on Card Made From Krupp Stahl

Period German pen nibs on card. Most of the nibs are made from Krupp V2 A Stahl. Krupp is better known for cannons. There is also a glass pen nib and a Pelikan ink advertising envelope with some ink staining on it. Unfortunately, the card is missing several nibs but overall it is still a nice piece. The card measures about 5' by 5 1/2'.
