Is this a manga? I am talking about the drawing

I don't really know, I searched for this picture in google but didn't get any real results... I found some results that had nekoka danshi no shitsukekata as the manga but I'm not sure if it' not only in it as a recruiting page too. Haven't had time to check that yet :/

Thank you both of you
