Or maybe have it with a disclaimer, or you are to disrespecting the original owner. Because others may not know it isn't part of the original cover.
Keep it original or say on the cover it is not original and the cover has been modified.
High resolution (original covers) links please.
Yes i did mean jewel cd cases, which is why i said the cd case back cover is nice to have also, as it has the edge for the jewel cd case, easy id.
