Our Whale & Nautilus card is a celebration of the sea with a nod to Fibonacci. The great blue whale rises toward the tides, directed by the moon. A nautilus shell is the perfect balance. I call this artwork, "Sacred Mystery." Perfect for birthday or any occasion. This 5"x7" card is blank on the inside and comes with a matching envelope. Also available as fine art print, 8"x10" signed. ©Suzanne Gaadt.
