Hi Brian,
Thanks for posting, That is interesting, the small lines show they were cut from the same sheets. I found your Young online with a search (only found 4-5 different cards on Google), but didnt see the lines until you pointed them out. The only other cards I located was the Gehringer that BMW has for $1K.
They are tough.
BTW I just measured them to a tan S&S.... They are 3/16" taller that what a "finished" S&S card would be if cut.
