Older Official Envelopes: Not In Scott?

Here are some older envelopes I cannot find in my Scott catalog- has anybody seen these before?

I have not seen those particular examples before -- and they are certainly collectible -- however, I do point out a statement at the beginning of the "Official Envelopes & Wrappers" section of the Scott Specialized Catalog of US Stamps that states, in part:




I can only assume from that statement that the Scott publishers decided only to include in their catalog only those envelope examples that contain a denomination (which your examples do not).

I'm sure there's a specialized catalog, probably from the US Postal Stationery Society, that has detailed listings about them, but you won't find them in the Scott Catalog.

These are attractive pentalty envelopes. Official usage, but not official stamped envelopes.

They are official Government department envelopes that do not require franking. The marking in the upper right corner looks to be a "Penalty for private use" Stamp as it served as a reminder that only official business received the free franking privilege. Since there is no franking on the cover, it will not be in Scott's.

"I'm sure there's a specialized catalog, probably from the US Postal Stationery Society. . ."

Sorry. No catalog. Everyone wants one. The research effort required to pull it off is huge.

Perhaps if they did it department by department...
