The Repeating Portrait

It looks like this rather nicely done portrait made two appearances in the series, as did John Hart, the actor playing both roles.

John Hart as Dion

The portrait as Dion in #227, TCOT Thermal Thief. That's Maxine Nichols (Nina Shipman) in front.

John Hard as Jamison Selff

The portrait as Jamison Selff in #250, TCOT Wrathful Wraith.
