There can only be a few of these that ever existed. Wilson size 6 and 7/8 cap was made in 1961 and worn in 1962. Lots of use. Ken’s number 16 in faded pen under the brim. Cap appears to also have a very faded 26 under the bill also which would make it a recycled Billy Williams cap also. We know for sure that Hubbs did wear this cap-it came right from his family!
