Two of my kids and I have visited colonial Jamestown and colonial Williamsburg. Element suggestions - musket, lace, white fence, things made of silver/pewter (gravy pitcher or tin cup or buttons), mop cap or straw hat, a colonial flag with 13 stars, wooden children toys (hoops, top), maybe a masted sailing ship, rag rug, church window
Maybe an outline of the colonial Williamsburg governor's palace
or colonial building from Jamestown
