While last week's coronation sampler featured a heavily embroidered gold coach, the examples I've seen of this one generally feature the coach done mainly in red. As a whole, it's a bit more lavish/whimsical/embellished than last week's design.The photograph often looks as though it's from a newspaper - I wonder if the design was originally from a newspaper? I've seen a couple of different photos used in this design, but this is the one I've most often seen. This image is from a past eBay auction (the item sold).
My guess is that this was a transfer design, and not sold as a kit, as I've seen variation in colours used on it which imply that while there was a colour picture for guidance, the final choice was the embroiderer's.
If you know where this design was published, or any more information, please do leave a comment.
