Census of 1c Blue, Type I (Scott 5)

Notes:

Crease between stamps that does not touch the 7R1E, but touches extreme left side of 8R. [Condition based on personal examination by Scott R. Trepel in July 2001].
Tied by two strikes of black “New Haven Conn.?Mar.”?cds. The circular is dated Feb. 25, 1852, soliciting contributions to the Linonian Society of Yale University.
This is the only known cover bearing a pair of 1c 1851 stamps, one of which is 7R1E. The use of this pair is particularly scarce and desirable. The 2c postage pays the over-500 miles unsealed circular rate, examples of which are rare. Printed circulars generally were not the type of mail that was saved, and most circulars were mailed within a 500-mile radius, which required only 1c postage. Even without the 7R1E, this cover is an unusual postal usage. It is also the only known 7R1E cover with any 2c rate.
