How about getting an anniversary gift set for your husband which includes a calligraphy starter kit along with a personalized calligraphy art piece? You can include a beautiful calligraphy pen set, some high-quality paper, ink, and a beginner's guide to calligraphy.
To make it more personalized, ask a professional calligrapher to create a custom art piece with a personalized message, maybe your wedding vow or your names. You can then frame it nicely and add it to his workspace or study.
You can also enroll him in a calligraphy class or workshop, so he can learn from a professional and take his skills to the next level. This could be an amazing experience for him as it could help him practice and learn new techniques, and he can enjoy the creative process of calligraphy.
Or you can get him a star map with the date of your anniversary.
