Change Blindness in Advertising

I'd not seen this fitting example of change blindness before:

I didn't see a single thing. More on change blindness.

I thought I was pretty on the ball when I noticed the bear was replace with the knight. Completely missed the 20 other changes though!

Errol Morris wrote a very interesting piece on this subject not too long ago. Not sure if you had seen it.

After a quick skim I can see it's a brilliant and lengthy post, thank you Errol — it's now in my to-read list. :)

WOW I was not even aware of the term change blindness let alone see any of the changes, how interesting and a little disturbing! :)

I saw only five changes: bear->knight, clock lying beside the dead guy turning into something different (I can't see exactly what it is) - but I didn't notice that the dead guy himself is different! - the items held by the old lady and the guy and different flowers on the table...
Amazing trick... ;)
