This is Batman 16, published by Mimosa (SA Magazine Co) +/- 1960.
Possibly as a money-saving exercise, these comics followed the Newsprint Series (see link below), as being printed in Digest-Sized.
It reprints the cover and the following story from DC Comics' Batman 135 (1960):
"The Menace of the Sky Creature"
Also reprinted is this story from Detective Comics 280 (1960):
"The Menace of the Atomic Man"
24 pages, glossy colour cover, black-and-white newsprint interior pages.
These titles were printed in a smaller size (165x109mm) compared to the original DC Comics title.
The printing reproduction from the original was very good quality.
Here is the cover of issue 16 and DC Comics' original cover:
