Rivet Punching from Titanic
Titanic’s hull was made of steel plates fastened with iron rivets. Each plate had many holes drilled so rivets could be driven in. Some of the steel pieces punched out like the hole in a donut were kept and presented as mementos usually with the ships name engraved. This rivet punching from RMS Titanic was set in a wooden star shape perhaps representing the White Star Line set on an oak shield.
