bittersbottles I have a amber colored fish shape bottle, 9.75" tall. It appears to have a logo on the bottom with a diamond with a roman numeral one inside.
Chris Thanks for posting. Please see this recent post discussing the same bottle - it has lots of detail. Yours appears to be lighter than most and more yellow-orangy than is typical. Definitely better than average. https://forum.antiquebottles-glass.com/discussion/comment/3307/#Comment_3307
