Glass Works Auctions Premier Auction #157 will be a two-part, timed closing affair, with part one slated for Monday, April 25, and part two to follow the next day, Tuesday, April 26. The online-only sale is packed with 263 lots of flasks, bitters, inks, target balls, fire grenades and black glass. Online bidding will be through www.glswrk-auction.com. Expected top lots include an Old Sachem Bitters and Wigwam Tonic bottle, estimated to change hands for $20,000-$30,000; a General Frank Cheatams Bitters bottle (Nashville, Tenn.) (est. $6,000-$8,000); a Travellers Bitters bottle (ca. 1834-70), with motif of a walking man (est. $8,000-$12,000); and an eagle New London Anchor Glassworks bottle (est. $8,000-$12,000). The General Frank Cheathams bitters and the Travellers bitters (with the likeness of General Robert E.

Hagenbuch pointed to another important bottle in the sale, a blown three-piece-mold geometric pan in cobalt blue (est. $7,000-$9,000). The cobalt blue blown three-piece mold pan is of extreme importance to collectors of early American glass.
