Who designed the "original tiles"?

[Blasphemer]

Since the rest of tiles found in version 4.2.5 have a particular name to them, I was wondering who had been responsible for designing the ones labeled "original tiles". Was it Adam Bolt, as well? I've read something about him having designed an early version, so maybe he meant those. Thank you.

This is not a definitive answer, but there's this comment at the start of lib/tiles/old/graf-xxx.prf: "Adapted from the file "graf-ami.prf", provided, along with the original pixmap file itself, by Lars Haugseth".
