It may be that other work by Beatrix Potter will be available to view at the V&A's new facility, the V&A East Storehouse in Stratford, when it opens on 31st May 2025. You can't check at the moment, presumably not until it opens, but the storehouse is designed to make available to view a lot more of the huge collections the V&A owns. You can find out more here -https://www.vam.ac.uk/east
And thanks for this thread, as it drew me to the V&A website where I found a collection of photographs of Preston Bus Station they hold. It's a masterpiece of brutalist design, once the biggest bus station in Europe and a building close to my heart. I will have to see that as soon as the museum opens. Sorry - that's completely off topic!
