Should these paintings be kept out of direct sunlight?

Ultraviolet light degrades oil pigments and accelerates the yellowing of varnishes over time. Hang works away from bright south facing windows. Stable indoor humidity also prevents wood panels and canvases from warping.

Are original frames important?

Period frames complement the aesthetic and historical context of the artwork. Many retain original gilding that matches the era of creation. Matching frames also protect the outer edges of canvases from physical damage.

How can I tell the age of a painting?

Examine the stretcher bars, canvas weave, and framing materials for period characteristics. Signatures and exhibition labels verso also help date the work. Craquelure in the paint layer often indicates age but varies by storage environment.
