In what will come across as a rather stunning development, some unexpected materials have been found on books meant for children.
These are the photos that have caused quite a stir on social media recently.
The photos show the obvious placement of condom ads on the back of a drawing book meant for kids.
The photos were shared on a popular online forum in Nigeria by a concerned user who said he saw them on his niece's books.
Below is what he had to say about his discovery:
"Guys what is happening?
"I picked up my niece's textbook and what I saw used as the cover amazed me. I mean this is a girl in primary school, between 7-9 years old.

"I had to use a paper to seal those places.
"Kindly always go through what your young chaps are reading and having access to.
"Things are getting crazy..."
