I don't know where bạn can find that exact comic, but if bạn know what năm it was in, it will be easy to find on Comics.com
Even if bạn don't know the year, bạn can still tìm kiếm for it. Here's the link: link The website reposts all the old comics, one per day. There's a tìm kiếm bar where bạn can put in the year, ngày and tháng to look for the comic. Good luck, I hope this helps.
