This unique triangular cobalt blue poison bottle is embossed with the Owl trade mark logo on on side, "The Owl Drug Co." on the second side, and "POISON" on the third side. This is the first iteration design, as it was later discontinued and the "The Owl Drug Co." embossing was moved to the same side as the owl logo, above the owl. This bottle specifically is the "one wing off-center" variant.
