Okay, it’s not really me. And it’s not really my friend.
But when my friend (who looks uncannily like the little spoon) sent it to me, I couldn’t stop laughing, it is us.
I haven’t been able to identify the artist yet, but I love the work, and love that entire advertising panels in Swedish subways are dedicated to art like that.
UPDATE: It’s Liv Strömquist’s work. Detailed here: https://www.theguardian.com/cities/2017/nov/02/enjoy-menstruation-subway-stockholm-art-row-liv-stromquist
