I can recall getting statically linked binaries of an early Motif-based GIMP on the "bonus CD" that came with a '90s Linux book which included Slackware on CD. The early GTK-based versions did look more modern, in a 90s way, but the benefit was that you could actually build them reasonably. Lesstif was sort of late to the party, and then was soon superceded when real Motif got opened.
