I'm making something for my brother. It seems I've got to engrave or tattoo something, but first I must do it on a stone slab. I have the white stone slab on my hands, and have to inscript two things. I have a thick black felt-tip pen. I mess up on one side, so I flip it and write on the other. The only thing I remember was the word GTA20D, which was the name of a band. For some reason, though, the T was supposedly an stylized interrogation mark, so it'd be written G?A20D. I messed up on the second time too, putting the ? on the wrong letter (I substituted the A, instead of the T). It was partially dislocated, on checkered boxes, likeso:

_______|2|0|D|
|G|T|?|
