Here are 2 butter tubs, in 2 sizes and hand painted by the Zenith Factory both before probably painted before 1960. The larger butter tub is in excellent condition and the smaller one, which is more like a trinket box, has a small chip in the underneath bottom edge. The larger tub is about 3-1/4 inches across and a little over 2-inches tall, not counting the top. The smaller tub is about 2-inches across and 1-1/4-inches tall. Both are signed by the painters.
Zenith was located in the town of Gouda. By the early 1970's the factory was no longer painting their delft by hand. The company closed their doors in 1984.
