This logo appears on several of the chapter covers for the Dragon Ball Manga by Akira Toriyama. It appears for the first time in chapter 200 released in November 1988. I suspect that it may be hand drawn by Toriyama but I have no way to verify this.

I have been successful in finding the correct fonts for a few of the other logo variations so it is possible that it is an official font, hence why I came here. I do not think that the letters were originally meant to overlap each other as they do in this image. I suspect that it was probably an editing choice, so if anybody can find the same letters but they happen to be spaced out from each other I will consider it to be the same font.
