I believe the handwriting on this cover is that of Clara Helff whose name appears on a number of FDCs. She and Siebold had a working relationship at the Patent Office. Note that this cover has the same 12 noon postmark as those found on the three Siebold FDCs.

Some of the FDCs associated with employees of the U.S. Patent Office have the Patent Office corner card.
