Fewer than in the earlier ones, but here we go:
The comparison of the malign hunchback Punch with Stickleback is pretty obvious - however, you may not know that the figure of Mister Punch derives from the Harlequin - the unpredictable trickster figure of the Comedia dell'Arte.
Some of this was covered by lettering, but from left to right we have a giant stone head of Hastur from Leviathan, a poster advertising The Circus of Dr. Lao , A portrait of Capt. Jack Dancer from Red Seas, the After Eight Ormolu clock (between Stickleback's feet), Kali from Ray Harryhausen’s The Golden Voyage of Sinbad and, symbolic of Valentine Bey's situation, a Greek vase showing Herakles battling the Hydra.
I messed up here; this should have been Festive Road, home of Mister Ben (from the 1970's UK children's TV series of the same name.)
