Yesterday was the official announcement for the LEGO Colosseum (10276) and in the press release, it said there was a free gift with purchase Roman Chariot set when you buy it during the Black Friday 2020 promotions starting on November 27. We know have a clear image of the set courtesy of a LEGO Store flyer. As you can see above, it shows a chariot pulled by two brick-built horses. It also includes a Roman minifigure as well. The promo will run from November 27-30, while supplies last. Thanks to John for the image.
