To continue, the blue, 2.5-Piastres(w/gutter!) Cyprus issue is in fine condition, but looks to have some gum residue on the gutter portion. The CDS from the Kyrenia P.O. is quite fine, though a bit light/faded with time. 

Lastly, as for the envelope, itself, it's in fair-good condition. It does have some stains on either side from some unknown source(s)(possibly glue). There are a number of creases in it, and a few, small tears in its edges. The back flap is intact, but does have a few, small tears in it, too. Noted imperfections aside, this is still a pretty neat, unique piece of Cypriot and Texan postal history!
