Even posting an innocent and 100 % relevant comment in another sub , at worst , is going to get downvoted to oblivion . <| sep |> Copyright doesn ' t expire when a product is no longer commercially available . Somebody may still own the rights and they could take action . However , it is unlikely if they have no financial incentive to do so now if you were a publishing company making millions , they would have financial incentive . One example that comes to mind is in retro gaming . A few companies now make custom cases with sleeves to insert slightly modified versions of the original box artwork , and there are many sellers on eBay that sell these cases with the artwork included . It protects the buyer ' s collection and makes it display well . However , owns the rights to that art , so modifying it and selling these cases is reproducing something you don ' t own the rights to for commercial gain . However , I ' ve yet to hear of anybody getting into trouble for doing this over the years . Nobody that owns the rights to this art is going to decide to suddenly print fresh cardboard boxes for 30 year old game cartridges , so the activity is ignored even though the companies are well within their rights to shut it down .
