I would appreciate if you do not post the same thing multiple times.
Please see this recent post of a nearly identical decanter

Yours does not have labels which is a minus to value. In general clear decanters like this from the 20th century are darn common so it is a take-whatever-you-can-get approach to value.
Like the other, yours does bear some resemblance to the very collectible "I Dream of Jeannie bottles
