Hale & Co., (5c) Blue, Street
Address Omitted (75L5). Position 15 on Second State plate, cut to
shape, tiny red ms. "E. S. Dans." overprint in blank address space,
initials of E. W. Simpson, Hale's agent in Danvers Mass., tied by framed
"Collect Six Cents for Hale & Co." handstamp, brownish "Forwarded by
Hale & Co. from Danvers" oval handstamp on folded cover (front with
part of four flaps) to Brooklyn N.Y., street address added by Hale's local
delivery agent, sealed tear at bottom left, file folds, neither affecting
stampVERY FINE. ONE OF TWO OR THREE EXAMPLES OF HALE & COMPANY'S DANVERS OFFICE HANDSTAMP. THIS IS THE ONLY STAMP KNOWN WITH THE DANVERS OVERPRINT. AN OUTSTANDING INDEPENDENT-MAILS USAGE.
Michael Gutman reports another Danvers cover, addressed to S. H. Low in New York City and docketed "1844/E. W. Upton/Aug. 26 Danvers", with 75L5 tied by the framed Collect handstamp. A third Danvers cover has been reported, but not confirmed. To the best of our knowledge, this is the only example of a Hale & Co. stamp with the Danvers overprint, which was obviously applied to stamps before use.
The stamp on this cover comes from Position 15 in the right vertical column. It does not show the plate damage found on this position on the Third State plate, therefore, it is a Second State impression -- from an early printing after the plate was modified by deleting the old address -- and probably dates from the summer of 1844.

(HARTFORD CONN.) Forwarded by
Hale & Co. from Hartford. Red oval handstamp -- much clearer strike
than usual -- matching "Collect Six Cents for Hale & Co." framed handstamp
on undated folded cover to Boston street address, file fold, Very Fine,
extremely scarce (Image) 
(HARTFORD CONN.) Forwarded by
Hale & Co. from Hartford Conn. Red oval handstamp on two folded
letters, one Dec. 20, 1844 to Troy N.Y. with Albany Collect handstamp
faintly struck in red, other Jan. 21, 1845 with red Collect box uprated to
12-1/2c, file folds, Fine-Very Fine strikes of the scarce Hartford oval (Image) 
(HAVERHILL MASS.) Hale & Co.,
(5c) Blue, Street Address Omitted (75L5). Two, one has red script
"h" initial and other has ms. "Haverhill" overprint, both
applied before use, each stamp cut to shape and tied by red Collect box,
matching bold strike of "Forwarded by Hale & Co. from Haverhill" oval
handstamp on folded cover to New Bedford Mass., docketing indicates Sep. 2
(1844) origin date, file fold thru both stamps, otherwise Very Fine, each
overprint ("h" and "Haverhill") is extremely rare -- the combination of the
two is extraordinary and suggests that first stamp was applied by the
sender and second was used to uprate the letter at the Haverhill office (Image) 
Hale & Co., (5c) Blue, Street
Address Omitted (75L5). Position 17 with "Wail" for "Wall" variety,
Second State of plate (undamaged), slightly irregular right margin but
clear to large on other sides, ms. "C" initial probably applied as a
cancel, brownish "Forwarded by Hale & Co.'s Great Eastern Mail" oval
handstamp used in conjunction with bold red "H. T. Crofoot's Newburyport
Letter Office" oval handstamp on Oct. 16, 1844 folded letter to
Worcester, turned and re-used from Worcester to New York City with
Hale's red Collect box -- the first letter is from John Balch to his
brother, Benjamin, coldly informing Ben he will not lend him money, in
response, Ben has forwarded the letter to Josiah Hale in New York City,
with a letter explaining the situation and referring to his brother with an
anti-Semitic slur -- file folds thru stamp, still Fine, a very scarce and
unusual conjunctive usage (Image)
