Santa And Sleigh Color Shift

Has anyone else seen or heard of these color shifts on the Santa and Sleigh Booklet?

Yours is the first one I've seen on the Santa & Sleigh booklet, but they are quite a common occurrence in modern US stamp issues. Are they collectible? Sure. Are they valuable? No. You'll probably see a lot of them throughout the Holiday Season.

Since the color misregistration on modern US issues are quite common, it would probably be classified to be a "freak" rather than anything else. Very seldom do you see any premium attached to it as the color misregistration is not that significant and most collectors would likely prefer a perfectly aligned copy for collecting purposes.
