Portrait of Quentin Collins

From The Dark Shadows Wiki

The Portrait of Quentin Collins was rendered by Charles Delaware Tate and commissioned by Count Andreas Petofi. At the time, Tate was unaware that his canvases often had magical properties, imbued by the power Petofi had given to him. As Quentin Collins was not interested in having his portrait done (painted portraits were a bit passe by then, cabinet cards being the current vogue, but loosing popularity to snapshots), the portrait was done from a photograph, augmented by one chance meeting between Collins and Tate at Collinwood, which ended with Tate being forceably removed (804).

During a Full Moon, the image of Quentin Collins would turn into a werewolf, and miraculously, Quentin would not turn into a werewolf at that time. Furthermore, the portrait began to age instead of Quentin, making him effectively immortal.

The first person to see the painting transform was Charity Trask, although it was a brief occurrence, and Tate did not see it happen.
