Lucretia P. Hale's story "The Peterkins' Christmas Tree" tells about the Ornaments used in the 1870's. Some still relevant today. "There was every kind of gilt hanging thing, from gilt pea pods to butterflies on springs. There were shining flags and lanterns, and bird cages, and nests with birds sitting them, baskets of fruit, gilt apples and bunches of grapes".
However, nothing beats shopping in quaint and unique 'Brick & Mortar' shops
with shopkeepers who can tell you
The Story of Christmas Ornaments.
