This HTC One (M8) limited edition is not for sale
HTC has been known to produce some other well received limited editions before. Back in 2010, the T-Mobile myTouch 3G was available in a finish that resembled a Fender Guitar. One of the most eye-catching limited editions produced by HTC was the black and white HTC One X designed by Cushnie et Ochs. That model was given away in a gift bag to celebrities attending Fashion Week in New York back in 2012.
This year, HTC gave away a limited edition HTC One (M8) with the iconic S.H.I.E.L.D. etched on the rear of the device. Only 14 units were made, and were given away as part of a contest to promote last May's Captain America movie.
