Ok...I bought the Godfather novel today....it was printed in 99 I think and I think the publisher is arrow....I think it could be the "blurry" cover. The cover looks like this :
an grey-haired man in a black suit standing in front of a large window with his 2 hands leaning on a desk in front of him....the light from the window blurs the image of the figure and is reflected from the desk.
The cover has the name Mario Puzo written in large red font in the centre of the cover and nearer the bottom of the cover "The Godfather" is written in a smaller, white font.
This seems likely to be the "blurry" cover but Im not sure if it is published in the US or just in UK and Ireland.
I went onto the site of the publisher but couldnt find a picture of the cover but I found a nice picture of Mario Puzo:
