Okay so here is the cover art for issue number 4 of Futaba-kun Change, plus from issue number 3 & 4 some other stuff.
Now I'm not sure if he did this in the Japanese publishing, but in the American printing Mr. Aro would talk about the people he worked with or works with while creating manga. It was a nice glimpse into the life of a manga creator. If these aren't interesting I won't show any more, but he included these in nearly every issue of Futaba.
Japanese original edition also includes these pages which you posted.
Typical manga has odd pages in the magazine, and publisher add one page of advertising to make it easier for filing. But they eliminate these advertising when they make graphic novel. Then most of the case, Manga creator made such kind of page as a sort of customer service.
I think the person who actually made the page which you posted is in this community. I bet he must be pleased when he saw it was published in U.S.
The photo 時をかける`Д´症状 san posted is the actual page he made before. (Futaba-kun Chenge Vol.2) He is the person who worked with Aro Hiroshi.
Unfortunately, I only have vol. 3, 6 and 8. If I have the vol.2 of English edition, I could post the English version of his page. (I left all volumes of the English Edition in Japan, I will post his page when I return to Japan.)
The another person he linked is the person who made the page you posted (middle one).
