Some sort of pesticide, I assume. One of my mom's favorites - it depicts a bug in high relief getting speared through. The bottom has an X-shaped mark.
My uncle entered it in a contest at a county fair and won a prize. It has a wooden stopper in it. My mom had "loaned" it to him with the stipulation it be returned to her when he passed. I am now in possession.
It's 5.25 inches tall. probably from the 1970s. I have a vague memory of its somehow being related to a coffee brand like Nescafe. I saw one on Poshmark, but the seller didn't provide any info other than the size. It has a T in an inverted triangle on the bottom. but the jar is too modern to be...
This one has a cork top and is about 3 inches tall. It may have had a paper label at one time - there is a shield-shaped raised area on one side. Bottom reveals much thicker glass on one side than the other.
Yep, I have one also. They are fairly common, judging by the seen online. Mine must have had a paper label, it only says "CARBONA" on the bottom, but it is 14-sided.
My aunt was an accomplished artist. I did her estate when she passed about 10 years ago. Her home was filled with small knickknacks and trinkets which I believe she collected with the idea of using them in still life paintings. I saved these from the "dreaded dumpster".
