I have one....lol, and what I would expect is NOT the horse in your picture. I would guess that is a Percheron cross. They started off about 25 yrs ago, at least in MD, to the best of my knowledge through the breeder I got mine from, breeding them for field hunters. She bred many, including a stallion BFF Incognito, who were fabulous both at eventing and hunting. She started out with the 50/50 crosses, and then refined it some and seemed to find (I didn't discuss it with her, but can only say what she ended up breeding and selling) with a 75% TB and 25% clyde.
Mine is the best big lap dog anyone could want.. Truly a wonderful gentle boy. He is now retired at 22 yrs old. No shoes, ever, gets fat on air, and the easiest keeper I have ever had. He raised my daughter, and was smart enough to know to test me, not her, and took fabulous care of her. Just a good boy, and the barn favorite.
As a sidenote-I was at a driving show a couple of years ago, and saw what they called "Clyde light", which made me chuckle, like "Bud light'? Anyway-they look just like a Clyde, but are smaller, being Hackney only crossbreds. However, they still had HUGE feet, at least in proportion to their body and legs.
