(Pictured next to the smallest of recent jars, the 57g). This is a beautiful little gem. A 1920’s 1/2 oz is about 15g. A flip tin lid and label that says Vegetable & Yeast Food Extract brings it to a very early glass jar. One this small could have been a sample jar, but I will need to find out more. It is a little jar that really make me smile, I could even put it in a necklace
