If you can get your hands on these books, please do! They’re by the Empak Publishing Company (Empak Enterprises, Inc.) and I believe there are ten books total in the series. They’re most likely out of print now (mine are from the 80s) so you’ll have to look for them at a used book store or online.
What I love about these books is that they cover so many great topics like Historic Black Women, Historic Black Firsts, Historic African Kings and Queens, Historic Blacks in the Arts, Historic Black Educators, etc. Below is a sample page from A Salute to Historic Black Women (Vol. 1 in the series).
