Architectural Digest writer Christopher Mason has created a casual survey of styles, periods and artists that the art market has not been "nice" to lately.

The current frenzy for modern and contemporary art, from post-war to Pop art and mid-century design, has left a lot of room for new collectors to acquire a wide range of art and historic objects at decent prices.

Japanese woodblock prints, 18th-century French furniture, and Old Masters are a few categories where prices are not as inflated for top-notch examples when compared to modern and contemporary art counterparts, according to Mason.

“We’re not generating many new collectors in premodern American art and furniture, either,” art dealer Debra Force tells AD, although even some early American modernists have been "overlooked." Writes Mason with Force's feedback:

So now is an ideal time to pick up the paintings of Gilded Age American artist Mary Cassatt (“suffering dramatically”), Hudson River School stars such as Asher Durand (“selling for half what they used to”), and Boston and Old Lyme Impressionists (“either the major collectors aren’t collecting anymore or they’ve died”). And, she adds, the wonderful works of California Impressionists of the early 1900s “are still really collected only by Californians.”
