Jay Michael Cooney commented on this illustration in a Facebook discussion group, saying it was a good representation of the Yeti. Indeed it looks very much like the descriptions given of the Yeti, but it shows the Little Yeti (Heuvelmans' le Petit Yeti) at the size of the larger Yeti (le Grand Yeti).
It also does bear a good resemblance to my own reconstruction artwork, although in a more finished final piece of art. Once again, the name "Yeti" is completely vague and nondeterminative, and might be equally well applied to any number of unrelated things.
