WWII US military comic: "How to Spot a Jap," from 1942

An eleven-page publication illustrated by Milton Caniff (creator of the "Steve Canyon" comic). The Army provided this test to US
Soldiers stationed in China during WWII. Link.

Reader comment: BoingBoing reader Cris Edbauer of Addison, Texas says,

The characters were from Caniffs "Terry and the Pirates" comic which
IIRC later morphed into "Steve Canyon". Terry is the kid you can see
on the cover image.
The other thing, the "National D-Day Museum" in New Orleans has a HUGE
wall sized enlargement
of this comic on permenant exhibit. Its in the
Pacific Theater half of the Museum under the sub-section "Clash of
Cultures". The whole fighting one form of stero-typing by re-enforcing
another kind thing is really bizarre.

The first line of Cris Edbauer's comment "The characters were from Caniffs 'Terry and the Pirates' comic which IIRC later morphed into 'Steve Canyon'" is only partially correct.

Caniff did do both comics, but quit working on Terry when the newspaper syndicate he drew for grabbed the rights away from him–Caniff made sure everything in Canyon was owned by *him* and the strip has an entirely different central cast and started with a very different premise. There *was* one cross-over: on the 50th anniversary of the first episode of "Terry" a secondary character asks Steve what he's looking at and Steve replies he thought he'd seen some old friends. The second panel is a beautifully done silhouette of the cast of "Terry."
