I can tell you this piece is from the 50-60's and it was more then likely used by a florist to deliver fresh flowers in. Since it is not marked there is no way to know who made it or where it was made. These were mass produced to be used in the florist industry. It can be valued for what it is if you can tell me the size? .
Yes, I know that. That does not tell who made it or where it was made. If the 1 were inside a triangle it might mean it as International glass, if the one was more like an H inside a triangle it would be hazel atlas. The 1 on this one just indicates a mold or inventory number.
