Sorry I dont have a breed suggestion as of such
But I find it funny that people assume the breed has to be different to be a novelty to the public
Most of the time for people not "farm savvy" a sheep IS a novelty
A farm 15 mins from me runs huge huge lambing open days, he is very successful, he runs all lleyns, he was once asked why he didnt have some "different" looking sheep for people
The reply was simple
Lleyns look like "boring white sheep", however if you asked any child in the country or adult even to draw a sheep that is what they would draw, and that is what a sheep would be to them, white and woolly, they can relate to that
If the man had a pen on lambs and some were black, some brown and some white, the kids would always go for the white ones because that was what "lambs" looked like, we also found the same with chicks
We used to take chicks to schools for children to see/feel (for free, purely for the enjoyment) they all wanted the yellow chick because thats what chicks were
Some of the brown or multi coloured chicks didnt even get touched as the children didnt know what they were!
I find it very interesting, how I hear over and over how the lleyn is a "boring" looking sheep, but actually it is a "Sheep" looking sheep
My advice would be to look what is in your area, if you want rare then most breeds are rare for some reason or another, so will have downsides, small carcass, horns, wirey wool, etc but should taste good
IMO any breed that is naturally reared on grass and given as little inputs as possible is good tasting

I didnt get on with zwartbles and I am low land, they werent tough enough, found the feet prone to scald and the ewes really do need feeding, whether that's very very good grass or feed and the lambs grew legs for a long while before growing carcass, and in a market that eats and pays for the carcass.. they just didnt fit for me
A sheep that looks pretty and has a superb shape and is run commercially is the blue texel?
Apart from that I think every breed I could suggest wouldnt be classed as novelty/pretty

Good luck with your search!
