Created by Cumbria-based artist Lydia Leith, they come in a range of colours: red, blue. gold, purple and black. I've gone with the red-white-and-blue theme for the ones I acquired for my collection. Lydia has kindly signed them, adding to their cachet.
Press coverage was a mixture of intrigued, you-cannot-be-serious, and what-an-affront-to-the-monarchy-humpf-humpf. Lydia was, however, generally feted as someone who had lightened the mood and brought some quality, innovation and artistic insight to the otherwise mundane and tacky world of royal event memorabilia.
All I can say is thank you for bringing the noble pastime of sick bag collecting to the fore of the nation's consciousness! By way of context and contrast, I have added below some pictures of other royal bags.
