How about taking your boyfriend to an art exhibit or gallery opening as an anniversary gift? This would give you both the chance to explore new art together and create lasting memories. If you have a specific artist he likes or a specific exhibit that he's mentioned, buying a piece of artwork from that artist or an exhibition catalog would also make for a thoughtful and memorable gift. Alternatively, consider a gift certificate for a local art class, so he can explore his own creativity and learn new techniques.
Or you can get him a star map with the date of your anniversary.
