ACNH: Blathers has New Rewards For Museum Completion in Version 2.0
Blathers now has a framed poster available for each wing of the museum you fully complete. He gives you a free one for each wing you fill with donations, but you can buy extras from him with bells if you decide you want more. The posters are a little underwhelming and it was silly there was no reward before this, but better late than never. I haven’t completed the art wing yet, but the photo below has the fish, bug, sea creature, and fossil framed posters for you to see. Hopefully this will help you decide if they’re worth going after in your own game:
