The legend of the Sand Dollar... with some living more than 200 Upon this odd-shaped seashell a legend grand is told,about the life of Jesus, that wondrous tale of old.At its center you will see, there seems to be a star,like the one that led the shepherds and wise men from afar.Around its surface are the marks of nails and thorns and spear,suffered by Christ upon the cross; the wounds show plainly here.But there is also an Easter lily, clear for us to see,the symbol of Christ's resurrection for all eternity.Break the center open, and you will releasethe five white doves awaiting to spread good will and peace“5 Doves”
