your not thinking fourth dimensionally about this easter egg.
they would not bother shopping in a photo of the real b29.
the meaning of the b29 in the distance could signify the rapid progress of its construction.
perhaps photoshopped in at the last minute from the skin viewer or directly from the 3d modelling program?
or it could be genuinely there in game.
you never know!
its a great subtle easter egg in the pic though imo. nice one HTC.
