Your art labels should include your name, object title, and media/support/technique—at a minimum.
A retrospective of your work should also include the dates.
In a one-person exhibition, your name need not be as prominent on labels and you might, instead, make the title larger and put it before your name.
When showing with other people, distinguishing between artists is more important and names should be first.
If there are multiple rooms in the exhibition and your show’s title text doesn’t appear anywhere near your works, you might need your name on every label.
