Boys' and Girls' March of Comics was a give-away publication from Dell Comics/Western Publishing distributed freely to various stores around the country with the store's name printed on the back page. The link below shows that this particular comic book was distributed by the I. Sabel Agency of the Maxwell Shoe Company, with offices in Pittsburg, Youngstown, and St. Louis.
Indian Chief was a comic book which lasted for 30 issues, from July 1951 (issue #3) to March 1959 (issue #33). What are now considered non-PC comics featuring American Indians were very popular in the 1950s.
Boys' and Girls' March of Comics featured Indian Chief in at least four of their issues. Issue 187 contains just a single story featuring the Indian Chief White Eagle in "The Night Raider." I'm not sure if this is a reprint or if it is a story leftover from the earlier cancellation of Indian Chief as a separate title.
In either case, enjoy. (And while you're at it, stock up on Maxwell shoes.)
