The latest issue of the comic, ``Memin para presidente'' (Memin for President), was being sold in select Wal-Mart stores that have a large Latino customer base, Wal-Mart Stores Inc. spokesman Lorenzo López in Bentonville, Ark., said.
But the discount giant decided to remove the comic from stores nationwide on Wednesday.
``We understand that Memin is a popular figure in México,'' the company said in a statement. ``However, given the sensitivity to the negative image Memin can portray to some, we felt that it was best to no longer carry the item in our stores. We apologize to those customers who may have been offended by the book's images.''
The Memin Pinguin comic was part of a series of Spanish-language titles carried in Wal-Mart stores.
A Houston customer, Shawnedria McGinty, spotted the comic in a local store, and objected to the caricature-like depiction of the main character, a small boy with thick lips and wide-open eyes. She complained to a community activist, Quanell X, who got the attention of local media.
A telephone listing for McGinty couldn't be immediately found. Quanell X declined comment, but planned to make a public statement Thursday in front of the Wal-Mart store that sold the comic.
The comic, first published in the 1940s, revolves around Memin Pinguin, a small Mexican-Cuban boy whose street smarts and adventures reflect the life of a poor boy in México City. The boy, portrayed as a likeable rascal, earns money shining shoes and selling newspapers to help his mother.
The characters of Memin and his mother have been criticized as throwbacks to stereotypical depiction of blacks. It is not the first time Memin has sparked debate in this country.
In 2005, the Mexican postal service issued a series of stamps commemorating the Memin character. President Bush and several African-Americans, including Jesse Jackson, asked the Mexican government to recall the stamps.
Mexico's then-president Vicente Fox defended the stamps, saying Memin Pinguin was a beloved character embraced by all Mexicans.
The 750,000-stamp issue sold out within a few days of release.
