Cool Paul. Thanks for posting pics. CGC might go 6.0/6.5 with those corner creases on that Tec 10 Nice eye appeal otherwise. Love the green/purple logo which was not used to often in that color combo with many Pre-Bat Tecs....What other books does your friend have? I see that Tec 33 on the left side
unfortunately, while the book might "feel" like a VF, technically, with a hard/small color breaking cr bottome right, and the 4 longer/lighter scratch creases? top right (unless those are not on the book), and the spine stress, this book might push 7.0 cgc wise, with a little bump coming from the white pages!...
but, what is cool, is that they are "free" , so they are what they are, no need to speculate as I suspect they will remain free!
