This is Batman 18, 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.
The cover image is taken from splash page from this issue's second story.
It reprints the the following story from DC Comics' Batman 129 (1959):
"Merriweather Jones -- Crime Prophet"
Also reprinted is this story from DC Comics' Batman 131 (1960):
"The Dog that betrayed Batman"
Also reprinted is this story from DC Comics' Batman 132 (1960):
"The Martian from Gotham City"
24 pages, glossy colour cover, black-and-white newsprint interior pages.
These titles were printed in a smaller size (162x115mm) compared to the original DC Comics title.
The printing reproduction from the original was very good quality.
