Image description: Two illustrations making a simple comic.
Top image: A woman and a man. The woman is wearing a simple dress and is entirely colored pink. The man is wearing a simple shirt and shorts and is entirely colored blue. Both arebin similar relaxed standing poses holding up the peace symbol with their hands. The woman is labeled transfems and the man is labeled transmascs.
Bottom image: The two people are now facing each other with closed eyes. Their right arms are wrapped around each other with their hands clasped. There is text that reads, "Oh my God don't use duck tape for that."
