This is my interpretation of the statuette of Cthulhu, described by H.P Lovecraft in The Call of Cthulhu as:
This thing, which seemed instinct with a fearsome and unnatural malignancy, was of a somewhat bloated corpulence, and squatted evilly on a rectangular block or pedestal covered with undecipherable characters. The tips of the wings touched the back edge of the block, the seat occupied the centre, whilst the long, curved claws of the doubled-up, crouching hind legs gripped the front edge and extended a quarter of the way down towards the bottom of the pedestal. The cephalopod head was bent forward, so that the ends of the facial feelers brushed the backs of huge fore-paws which clasped the croucher’s elevated knees.<
The undecipherable characters on the plinth I directly traced from a drawing of the statue by H.P Lovecraft in a 1937 letter to R.H. Barlow, so they are literally in Lovecraft's own hand here! See this letter at: https://lovecraft.fandom.com/wiki/Cthulhu?file=Cthulhu_sketch_by_Lovecraft.jpg
