I am new to the site. I just recently purchased a persons bike seat and was looking for any info about it. It is apx 13 inches by 12 & 1/2 inches and has a METAL tag on the back that reads PERSONS LIC. UNDER U.S. PAT. D-204121. The bottom has MADE IN PERSONS U.S.A. a PERSONS PRODUCT and PERMACO 6329. It is in great condition any ideas as to the age or value or any general info is greatly appreciated.
