A rectangular white label is pasted onto the page, featuring a circular emblem. The emblem depicts a white pelican in its piety a mother bird feeding her young with her own blood, plucking its breast to feed three chicks in a nest. This is a traditional symbol of sacrifice and the alchemical work. Above the pelican, golden rays emanate from a sun or celestial source. Below the nest, a white square contains four red roses arranged in a grid. The central image has a blue background and is encircled by a green border containing the text "HERMETIC PHILOSOPHY" original: "PHILOSOPHIA HERMETICA".
