I just noticed the reason Amazon doesn't display the TLOUR image. The free digital copy of TLOUR is "Offer valid only when shipped and sold by Amazon.com"
Given they sometimes have a 3rd party displaying as the home page offer (cheapest offer?) it would be false advertising to show the TLOUR image.
That explains Amazon's lack of TLOUR promotional image. Not sure why other retailer who don't sell 3rd party stock wouldn't promote the TLOUR deal.
