Joe N. asked about this company and Dan W. suggested it was probably the
Frederick Post Co. of Chicago. I suspect Dan's right, but am sorry that
destroys part of the attraction of Joe's tool. But I do think Dan was
wrong about the Post Co. being established in 1921. The DAT shows them
starting in1889 and lasting until1972. It's quite possible they were
incorporated in 1921; while compiling the DAT, I ran into several cases
where the Est. and Inc. dates got mixed up.

Best,
Bob
