Art – Paintings, Sculptures and Prints

Paintings

Famous paintings by renowned artists are among the blue chip collectible assets that have demonstrated an ability to continually reach new high water marks at auction over decades. Works by Old Masters like Rembrandt and Vermeer and legendary 19th/20th century artists including Picasso, Monet, Warhol and Basquiat have commanded prices from the tens of millions up to even over $450 million in the case of Leonardo da Vinci’s Salvator Mundi. Even paintings that are not masterpiece level can still be quite valuable from established artists.

Sculptures

Like paintings, sculptures from famous artists both historical and modern grace the collections of top museums and discerning private collectors. Auguste Rodin, Edgar Degas, Henry Moore and Alberto Giacometti are just some of the sculptors whose works are highly sought after and can sell for millions depending on the size, materials, subject matter and rarity of the piece.

Prints

While less pricey than original paintings and sculptures, limited edition prints numbered and signed by the artist also command substantial prices from collectors and investors. Prints allow more participants to own art from blue-chip artists, although lower print numbers in the series are the most covetable. Prints from Andy Warhol, Roy Lichtenstein, and Japanese woodblock masters like Hiroshige and Katsushika Hokusai remain icons with devotees worldwide.
