Printed in U.S.A. by Western Printing & Lithographing Co. (per indicia)
There would seem to be an error in the copyright attribution appearing in the indicia, which says "Copyright, 1948 by Loews Incorporated." Other then-contemporary issues of March of Comics devoted to Walter Lantz properties (MOC #7 Oswald the Rabbit and MOC #16 Woody Woodpecker) bear the copyright attribution "Copyright, 1947, by Walter Lantz Productions."
The attribution "Copyright, 1948 by Loews Incorporated." appears in the prior issue of March of Comics (#21) devoted to Tom and Jerry, leading one to believe that the misprint in issue #22 is a "holdover" from its predecessor.
