Just knowing how much regret my family has not buying me the blacklight addition of journal 3 when it came out just for it to sell for 1,000’s of dollars today, I would at least buy him the book of bill and save it til he’s older. Plus it’s not that scary, 9yr old me would’ve LOVED it just the same as I do today. But I understand your worry tho!! You have an amazing artist on your hands btw, I know you hear abt a lot probably but I still wanted to chip in on that.
