Thanks for the advice adventure_rn. Apparently Oregon does not give out plastic cards for your license, so I couldn't refer to the card. But in the email I received from the Oregon State Board of Nursing that told me I was officially licensed listed it with the RN at the end, so I'll just include it.
And thank you about the name, I always wished I could find more ways of incorporating my hobby of visual art into my nursing career. So I love that your college friend was able to find a way to reframe the way she views her medical profession as an artistic one.
