For your husband's birthday, you could consider getting him an abstract painting by one of his favorite artists or discovering a new one that he hasn't seen before.
Alternatively, you could buy him painting supplies like high-quality canvases, a set of acrylic or oil paints, a new set of brushes or brushes cleaner, or an easel, so that he can experiment and create his own abstract work.
If he already has painting supplies, you could also consider booking him a private art lesson or a group workshop in your local community, so that he can learn new techniques and connect with other like-minded painters. It could be a fun and inspirational experience for him that would allow him to further his passion for abstract painting.
Or you can get him a star map with the date when he was born.
