I have to find a way to say "clasificables incógnito" in English. It refers to stuff found everywhere that will be used in art in a way not known yet. For example: match boxes, candy wrappers, labels, price stickers, etc. That is, stuff that is classified, but will be part of an unknown character in a work of art. My try is the obvious one, but I am not sure it makes sense: incognito classifiables Is that correct? Thank you.
