Contemporary art - almost all 275 lots of it of post-World War II vintage - will be offered at a sale beginning at noon Nov. 17 at the Rago Arts and Auctions Center in Lambertville. The three biker portraits, from a series by Helen Garber, are titled Gerri, Dan and Chops, and described by Rago associate Meredith Hilferty as representative of the "edgy work" emphasized at recent sales. They are expected to sell for $2,000 to $3,000 each.

Another "edgy" piece being offered is Fabian Marcaccio's Paintant #4, a water-and-oil abstract on paper and nylon stretched away from the wall with thin copper tubing. It is expected to sell for $20,000 to $25,000, according to presale estimates in the auction catalog. (View it at www.ragoarts.com.)

The top estimates are for works by more conventional contemporaries. The sale will open with five acrylic and silkscreens on canvas by Richard Pettibone, notably his Andy Warhol, Two Elvis, 1964, 1975, which has a presale estimate of $60,000 to $80,000.

In addition to 111 lots of paintings, drawings and sculpture - including a bronze cat by Louise Nevelson originally from the estate of the Trenton civic figure Mary Roebling - the sale will conclude with 160 lots of works on paper, prints and photographs. They include two Andy Warhol Electric Chairs ($5,000 to $7,000 each) five Weegee photos ($1,200 to about $1,600 each), and Marcel Dzama's screenprints depicting armed women and children and titled Citizens of Regimentation, 2004 ($2,500 to $3,500).

Previews will be from noon to 5 p.m. tomorrow through next Friday at the gallery, 333 N. Main St. For more information, call 609-397-9374.

The Liberty Bell replica will be offered by Freeman's on Nov. 18 as the last item of its three-day Americana and Pennsylvania Sale. Though the term replica is often misused, the "Bicentennial Bell" Freeman's is selling meets almost all the criteria.

Commissioned in 1975 by Edward J. Piszek, chairman of the Liberty Bell Foundation, this bell was cast by Whitechapel Foundry in England, which had cast the original in 1752 and did not break the mold. All it lacks is the crack, the auction catalog notes.

On July 4, 1976, the bell was rung by then-President Gerald Ford. In 1987, it was rung by Chief Justice Warren Burger, in 1989 by Lech Walesa, in 1993 by Pope John Paul II, and by Bill Clinton at his inauguration. The replica is being sold as part of the liquidation of the estate of Piszek, the founder of Mrs. Paul's Kitchen; the presale estimate is $20,000 to $30,000.

The first session of two devoted to Americana, beginning at 2 p.m. Nov. 16, will offer 121 lots of Chinese export and other fine ceramics, notably a porcelain punch bowl with a hunt motif ($16,000 to $20,000) first owned by Col. Thomas Sheppard, a Revolutionary War figure and later a China trade merchant.

The second Americana session, beginning at 10 a.m. Nov. 17, will offer 540 lots, beginning with scrimshaw; continuing with glass, furniture, tramp art and American Indian items; and ending with garden figures (no gnomes). Among the highlights: an Aaron Willard Federal inlaid mahogany tall case clock ($20,000 to $30,000); a John Belter rococo revival settee exhibited at the Metropolitan Museum of Art in 1934 ($25,000 to $35,000); and a mid-19th-century Upper Missouri River man's coat from the Nez Perce ($40,000 to $60,000).

The final session, which begins at noon Nov. 18, opens with books, maps and manuscripts, notably a first American edition of the first English-language translation of the Bible from the Latin Vulgate. Published in 1790, it is expected to sell for $8,000 to $12,000.

The session continues with Pennsylvania modern works, including items by George Nakashima and Samuel Yellin, and then settles down to the Pennsylvania sale itself.

A Philadelphia Chippendale chair from the collection of Helen and Walter Morgan is expected to sell for $8,000 to $12,000, a carved painted cherub figure is expected to bring $15,000 to $25,000, and a full-bodied metal peafowl weather vane $8,000 to $12,000.

Previews will be from noon to 5 p.m. tomorrow and 10 a.m. to 4:30 p.m. Monday through Friday at the gallery, 1808 Chestnut St. Information: 215-563-9275 or www.freemansauction.com.
