context: ZUN has made convention where it demonstrated several old sketches (same convention where ZUN showed the original Satsuki rin sketch and the whole fandom mistook it for a cirno prototype.)
at that convention, he showed an early sketch of Label girl, that sketch it is a full body sketch, and you can see that Labelko has ropes/strings tied to her limbs, you can also see that she was barefoot.
Unfortunately, ZUN did not allow photos to be taken of the original sketch.
but many good people redrew the sketch to give us an idea of what the sketch looked like.

the original sketch is believed to have been made in 2001 (the year DiPP was originally intended to be released, but was then delayed to the following year).
it is also noticeable that in all the recreations labelko has 4 toes, this is a mistake from the original sketch.
