ghost of the wild

So which side is acid free?? the slick or the dull?? Thanks in advance.

thanks bro

Sorry Iposted this in wrong place first but here goes again here, mabe admin or someone could also explain to me how to delete the other?? I'm real new at all this CGC so hope you guys can help guide me. I have a Wolverine Vol. 3 number 24 graded 9.8 that ,yes my dumb butt dropped it a very short juggle drop but now as is my luck it has a small crack running on the top back about 2 to 3 inches long. I want to get it re cased. I have never submitted any comics myself so this is all Greek to me. Do i first have to upgrade my CGC account to associate? Which I was going to do anyway cause I want to get some of my collection graded. Then I guess I choose the re-holder option? Then it says 15.00 but at the top it says a $5 handling fee per invoice applies to all online submissions, and an $8 handling fee per invoice applies to all PDF/paper submissions. so how much do I send them just to get this book re cased?? Please excuse my ignorance on all this and can someone who has done this or understands, guide me through what I really need to do here just to get this book done and back in it's original shape. Thank you to all who take your time to deal with me. Mean while I will be searching the site for answers as well. Peace
