I have a bottle that has on the bottom federal law forbids sale R-105 58-56 1 Q

It is for sale.

I would appreciate if you do not post the same thing multiple times.

Please see this recent post of a nearly identical decanter https://forum.antiquebottles-glass.com/discussion/comment/3071/#Comment_3071

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 http://www.ebay.com/bhp/jeannie-bottle
