Air China (tear off)

The Middle Kingdom's newest offering: a Southeast-Asian-style perforated tear-off strip to keep your bag spanking clean before you empty your half-digested meal into it. Plus a large red arrow to show you should tear across, not down.

The "WATERPROOF DISPOSAL BAG" at the top is upside down so you can read it while leaning forward over the bag.

There's some Chinese in the gusset: the bagmaker's name, perhaps? Plus a phone number: 0471 494 1197. Try calling this number if your bag has lost its tear-off strip and you need to order another one.

Air China (short arrow)

A simplification of the bag above: A shorter arrow at the top, and nothing in the gusset.

Air China (short arrow, sans-serif Tear Off)

The "Tear off" is now in sans-serif type. Ah, the subtlety of bagophily!

Air China (short arrow, sans serif...)

Ah yes, but the "Tear off" is in yet another typeface.
