For those not in the know, the Krewe of Excalibur used to throw handmade decorated shields. Similar to the Zulu Coconut, Muses Shoe, or Nyx Purse, many Krewes have a special throw that their riders throw. To have caught one of these throws should be considered a treasure, as you may only catch one, if any.
Here are some of the shields that I made through the years.
