Yes, but you didnt design them. The regime may have fallen (may I remind you political conversations are not permitted before it escolades), but the Graphic designer(s) still own rights.
Eg; I make a logo for say.. a crappy software that counts how many eyebrow hairs you have from a photo (Yeah.. wild, pointless imagination). The software developers go bankrupt. I still own editorial rights to that image (unless I have signed contracts, they have paid me etc blah blah.) I doubt youd be able to track down said documents for mere fpsc game content
