Yanukoych, who claimed he grew up without necessities, abandoned his 336-acre estate -- which included a castle, helicopter landing pad and a yacht -- when he was overthrown during a February uprising. He is now believed to be living in Russia.
The exhibition in Kiev features 518 objects from the homes of Yanukovych and his former prosecutor general, Victor Pshonka. Curators value the collection at over $50 million. The collection is part rare art and antiquities, and part kitsch.
The rarities include a collection of Byzantine religious icons, some dating to the 14th century; works by Picasso; rare and old firearms; and the reportedly priceless book Apostle by Ivan Fyodorov, published in 1574 and considered the first book printed in Russia.
The collection also includes 20 portraits of Yanukovych himself, a portrait of Pshonka dressed in 18th century Russian military uniform, a tennis racket made of gold, and a diamond-encrusted handgun.
