The winner, in what is the third annual staging of the Country Life-inspired event will be announced at June's Olympia International Fine Art & Antiques Fair.
This is the first time that a People's Vote has been introduced. The judges have drawn up a shortlist of 16 for the competition, which is being sponsored by Cadogan Tate and Besso.
The People's Vote, which closes at midday on June 3, includes automatic receipt of a double ticket to the Olympia fair, and entry to a prize draw.
