Single leaf measuring 12¼ × 7⅝ inches (31 × 19 cm). The letter was written on the verso of a copy of “A Fac-simile from the Book of Abraham, No. 2.,” a Times and Seasons broadside. It was folded in half and then trifolded twice in letter style and addressed. The letter was later refolded, presumably for filing.

Compression marks on the address panel of the Letter from Clyde, Williams & Co., between circa 1 and 15 July 1843, indicate that it contained an enclosure at one point. Although the text of that letter does not explicitly identify an enclosure, the compression marks and the comparative size of the address panels for both the Letter from Clyde, Williams & Co. and the featured copy—drafted as a response—suggest the draft was probably housed inside the folded letter and retained in that state among church records. By 1973 the document had been included in the JS Collection at the Church Historical Department (now CHL). The document’s presumed retention in church records and its inclusion in the JS Collection by 1973 suggest continuous institutional custody.
