ypsilanti company wicker set

I purchased a wicker set and was painting it and noticed a metal plate on back that read ypsilnti furniture company, Iona Michigan,I cant find any good information on it, but i know it was made between 1904 and 1945..it is white and there is a:

rocker

chair

couch

and table

all are very well made and looks great, the cushions are very  well perserved and are very springy and in great shape. It possibly was recovered at one point but the denim that they recovered  it in, has faded there are several pillows with it, i dont know if they are original or not.

Good
