I've got a red, a yellow, and a blue version! I have also seen a green one.
I once saw one of these peacocks for sale on a dealer's stand at an antique fair priced at £120 - and marked '1920s Libertys piece'. I asked the lady owner why she thought that, and she said that she knew nothing about paperweights (spot on!) had been given that information when she bought it for £80 from another dealer some time ago! I am pretty sure she was genuine, particularly from the gasps of shock when I told her the true origin, and that the value was much nearer 80 pence than £80!
