O Globo Juvenil Mensal #32

From Skye Ott:

Publisher O Globo Brazil 1943

The Earliest Timely & National Cross Over known to exist Globally.

This issue is most likely the 1st foreign inter-company original cross over story of American heroes.

Most of the hero stories in that era were WW II propaganda.

That would also contribute to its intrinsic cultural and historical value!
