I noticed there are already some #Museum30 posts on here so I thought I might as well share my photos here too! Museum 30 is a challenge where museum workers share photos that relate to various prompts. It was created by @/MagnifyZoology on Twitter back in 2017. This year's prompts are in the photo below and on this link: https://twitter.com/magnifyzoology/status/1586055316528984064
