Ruffled Bowl with or without Gold?

Ruffled Bowl with White Trim

These ruffled or scalloped or bent glass bowls (which ever you choose to call them) seem to be one of the most popular early Walt Disney World souvenirs based on how often I see them on ebay.

I have two versions of this bowl, the one above and on the left with white trim and with gold on the right and in the bottom image.  Both feature the same images, copyright and logo.

I'm not sure of the exact age of these pieces but I assume early 1970's since the Osceola steamship stopped running in 1976 and many of the images resemble artist renderings like those on the pre-opening postcards.
