I I have an M. Schulz upright piano with the same sticker that says "For the advancement of music" with serial number 000918. From what I have found this was used by different piano companies. I am not sure if each company had its own set of serial numbers for these stickers or if all the companies followed one set I'd serial numbers. Hope that helps some.
