Two marks sign the work of in vivo: the wordmark and the eye. Either one can sign a work alone. On print they appear together.

The wordmark is always lowercase, set in Neuzeit S LT Std Book Heavy. The final o is replaced by a solid circle exactly one x-height across.

In running text the name is set in the wordmark face with an ordinary o. The solid o does not hold at text size.

The eye is a circle with two tangents drawn back to a rounded point. The pupil is an open circle, a little under six tenths of the eye's diameter, set off centre, away from the point.

The in vivo eye: a black teardrop pointing left, with an open circular pupil set toward its round end, on a light grey ground.

Construction drawing in red over the eye: the outer circle, the two tangents meeting at the point, and the centre lines of the eye and the pupil.

The in vivo eye in white on black, the pupil open to the black ground.

signet, 2026, by in vivo. A ring seen from above: its head is the eye, the pupil open through it.
