Brand: X - Unknown
Made in: USA
Oldie made by Loewenthal's. Most likely a stationary store in the 20's.
I call these “Quazi” brands because I’m not 100% certain which company actually made them. Sometimes the pencils are stamped with a stationery store or maybe even the name of someone famous. But my hunch is they were produced by another company. If you have more information about any of these vintage pencils I would love to know!
