Did you find an Icepo? Please let me know at rakkadeer [at] gmail [dot] com, subject line "icepo!"
"Icepo 3" was placed in Dreaming of Iceland: The Lure of a Family Legend by Sally Magnusson, pgs 30-31. Chiswick Library, London, England.
I am getting my very own Icepo drawing to hide in a book in the Nashville library. The internet is so full of magic.
You guys I found my soul mate.
