This is Batman 23, published by Mimosa (SA Magazine Co) +/- 1961.
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 first story from DC Comics' Batman 137 (1960):
"Robin's New Boss"
Also reprinted is this story from DC Comics' Detective Comics 203 (1954):
"The Crimes of Catwoman!"
Also reprinted is this story from DC Comics' Detective Comics 217 (1955):
"The Mental Giant of Gotham City"
32 pages, glossy colour cover, black-and-white newsprint interior pages.
These titles were printed in a smaller size (187x131mm) compared to the original DC Comics title.
The printing reproduction from the original was very good quality.
