Found this Koufax card for all of $5 at a flea market today and am scuffing to identify the year and issue. I know these were issued over a period of years so it is possible no exact date or issue can be established.
The only other example I could find was in this Wheatland Auction (see link below) from earlier in the year.
Can anyone help me identify the year and issue of this item? TIA!
