Entertainment Tweet by @NESMUSEUM Published Oct. 20 2023 01:10 PM We love this quirky postcard that's just come into our collection. Dated from around 1910, it opens up to reveal views of Edwardian #Sheffield; 12 mini postcards for the price of one! #MuseumTwitter @CollectionTrust @Aimuseums #Collections #Museums, — National Emergency Services Museum (@NESMUSEUM) October 20, 2023 12:10
