It reminds me of the covering put over some logos on cameras brought back from Asia in the 70s. Customs required that because the official importer owned exclusive rights. If I recall, it was kind of a tape. You might see if that was removable and how.
I'd start with alcohol (still talking about the paint here, not for you). Then I'd try the compounds sold for removing dried paint; a one brand here are "Goof Off". Typically found in home type paint stores.
If these didn't work I'd progress to paint thinner, then lacquer thinner.
