It looks to me like just the 12C+ with some writing on it. The 25th Anniversary Edition of the 12CP used the same font, BTW. I think that these anniversary releases are a great way to sell extra machines to those of us that feel we need to collect every edition.
HP has a history of releasing anniversary editions, where just a label is added, of some calculators, the 14B, 32s, and 28s come to mind. Are there others?
