Failed cake looks like letter to King of Abyssinia

A baking pan containing an extremely failed, flattened cake with cracked yellow center and burnt curled edges that resembles an ancient parchment scroll. Text above and in the center jokes about intending to bake a cake but ending up with a historical letter to the Negus of Abyssinia.

Mocks an extreme baking failure where the food ended up looking like an ancient historical manuscript or parchment.
