Hush 'Sirens In Motion' A/P #1 Available?

Here is an image of 'Sirens In Motion' A/P #1 by artist Hush. This is a 24 colour 22 x 22 inch screen print on 300GSM Somerset Satin paper with an A/P edition size of 10. Apparently this artist proof numbered AP 1 is for sale but I am unsure where and unsure for how much.
