Looking for a Rien Poortvliet illustration from 'Secrets of the Gnomes'

I have been scouring the internet trying to find an illustration by Rien Poortvliet for the 1982 book 'Secrets of the Gnomes' with very little luck. The illustration is of a brood of baby trolls fighting while their mama plucks a bird. Here is the best I can find http://www.rubylane.com/item/440186-BK1990/1982-x27Secrets-Gnomesx27-DJ-1st-Ed o do you know where I could find a better quality clearer pic of this illustration online? Any help at all would be greatly appreciated.
