Yes, I don't remember the exact details, but I expected to just get them back via the group organizers, but it turned out they didn't retrieve them, but somehow in theory you could have gotten them directly from the exhibition organizers or something, but I never had any direct contact with those people, nor did I know how to go about it. I mean, that was before email was widespread, so I had no idea whom to ask or contact. And the group had dissolved by then, because it was like a final project type of thing. And as an adult I would be more persistent now, but back then I just didn't know what to do.
