Item arrived in v. good condition, book itself is chock full of references for drawing older men. The artists who include things like the way bodies change with age -- knobbier knees, looser skin, wrinkles, etc. A few of the drawings did seem more comedic than educational (particularly the cross-dressing ojisan), but overall, I liked it.
Minor qualm: This is no fault of the book's, as it was written for Japanese readers, but I wish there had been more information on the artists (credited by name in the back), since the two I really wanted to look up don't have a Pixiv or a Twitter and my Japanese proficiency isn't good enough to read the kanji.
Came in great condition and looked new for a used book. I love the variety of older dudes in it. It's more a reference book than a how to book. Either way it's totally worth getting!
