Description

When you cast this spell you touch an object and a willing creature. The object becomes a tattoo on the creature for the duration of the spell or until the creature wills the object to leave the tattoo as a swift action. The only size restrictions are the object is a full sized rendition of the object tattooed on the creature ie. smaller creatures can not have full sized vehicles tattooed upon their body. The object does not rip clothing when it leave the body, but appears next to the creature when summoned.

The tattoo is hyperrealist, so any creature who sees it will admire the work, but they will need to detect magic to understand it is more than a well done tattoo.
