"YELLOW BROWN SWEET CAPORAL 350/460 SUBJECTS FACTORY #30"
I own 6 of these type so far( matty, street, konetchy, Sweeney, snodgras, and Mcintyre) and another in transit....
5 of them ARE NOT AVAILABLE WITH THAT BACK!

(except for Matty super print).....
meaning.....YOU CAN'T HAVE A FACTORY PRODUCTION CARD WITH THAT BACK!
Street, Konetchy, Snodgras, Sweeney, Mcintyre- THEY do NOT have A factory issued sc 460 F #30 back!!
so, if you want to do a complete back run of one of the 33 KNOWN EXAMPLES sc 460 fact #30 , you would have to obtain one of these
btw...THANKS CHRIS B FOR IMAGES
