Artist sketch of my vagina?!

This is an odd request that I honestly have no idea where else to post to make this happen. Does anyone have any resources to go about obtaining an artists rendering of my vulva (not the vaginal canal).

My sister and I have a running joke where she wants no present more than to see my “vagina” to see if it resembles our mother, who passed away 20 years ago and prior to that, was very open and comfortable with her body.

My sister is turning 40 soon and I can think of no better present than to actually call her on what she has been insistent upon for 5+ years..
