This set of 4 ATCs was created for a song swap. The premise of the swap is that you choose a song and illustrate it in four cards. I found the first challenge to be choosing a song. It turned out to be a difficult task to find a song that could be neatly illustrated in four cards. In addition the lyrics must also be included on the card. I finally chose Love Potion #9, which has been a favorite of mine since I was a kid. At the bottom and top of each card is a niche that when pulled expands the card to reveal the lyrics. In the third card the bottle contains real ink and is sealed with wax.
