I regularly post about picture books that include a visible Muslim in the illustrations.  Often the text is about another character, or a larger theme, so I do not write an entire review, I simply highlight that Islamic representation is present.  I cannot figure out how to just highlight those hashtagged #muslimsintheillustrations but if you follow me on Instagram (@islamicschoollibrarian), or wish to browse by that hashtag on Instagram you will see those highlighted books and the pages where the rep occurs.
