The Sacred Heart has long been an iconic image to Christians and it's significance has not been lost on those who enjoy tattoos. This tattoo flash image represents the Sacred Heart of Christ along with several other amulet-like images.
Included are the number 13 under an umbrella, the evil eye protector, a skull and crossbones and a sparrow flying downward. All of these are popular tattoo designs.
A tattoo flash is a design that will be used for a tattoo (or, indeed, already has been used for a tattoo). The flash has been printed, painted or drawn on paper or cardboard. Pictures like these are hung on the tattooists walls for potential customers to peruse along with other designs.
