From the announcement:
All the King's Men Toy Soldiers is pleased to announce separate heads to make black soldiers. These pieces can be used from the American Revolution to the American Civil War, and beyond. We offer them for both periods; American Revolution and American Civil War.
There are four different "poses": bare, in tricorne, in floppy hat, and in kepi. Use them with our existing bodies from the AWI and ACW to create black Patriots or Loyalists, or volunteers from the Civil War like the 54th Massachusetts.
The heads are also available in their own sets or in combo packs for their respective eras. Head sets are $5 for 12 pieces. These figures are 54mm metal, and come unpainted.
