In Yunnan Province, this is a spectacularly scenic area and we assume all that would be reflected in this set of oversized (4-3/8″ x 8″) cards.  We just don’t know how many cards there are, because the set is firmly sealed in Cello-wrap that we don’t want to disturb:  the set deserves to remain as a set.  Our best guess — no guarantees, sorry — is that there are 20 unused cards.  The two photos we do see, on front and back, are wonderful.  Grade: 1
