Vintage IBM Think Sign Greek Red-Orange Original Box

Fun vintage IBM desk sign is "Think" in Greek language, and comes with original box. The Classic IBM slogan is printed on a silver tone metal plaque (aluminum, I think) that's attached to the older red-orange colored resin plastic sign. The letters of "Think" are impressed slightly in the lightweight metal and colored black. Sign is marked IBM on back and there's a space in the center for a foot so that it can stand up on a desk, which originally came with the sign. They are missing now though. I imagine it could be easily converted to hang on a wall if you want. The sign is in very nice vintage condition -- probably it was never used, since it was purchased in its original box. Above and below the foot holes are slight mold marks created during manufacturing. There is some light scratching on back and the box has discoloration and a missing end panel, also what looks like a grease spot in middle of one side Box stamped 520-1840, previous owner wrote "Greek". Sign measures 9" x 2 3/4".
