QUERIES: TREASURE ALBUM AND 1955 DDO MYSTERIES

I have a couple of requests for information about mystery items:

Treasure Albums

Ebay has been offering several of these rolled out cents commemorating "Treasure Albums - Originators of the Album Concept in Coin Collecting." Curious, I acquired this elongate on various dates of Lincoln Cents ranging from 1944-57, and most examples are well toned. The address in Riverside, CA includes a Zip Code, so it can't be earlier than about 1964. I suspect it dates from the mid-late '60s, but I can't find any information, and I don't know of any coin albums by that name. There was a line of plastic coin albums published by Ticker and Treasure in 1963-65, but that company was in Chicago.

H.M.L. 1955 Double Die Cent Envelope
The other mystery item is a 2-inch square paper coin envelope imprinted in red for a 1955 Double Die Obverse (DDO) cent. I acquired a stack of almost 50 pieces, but I don't know who produced it or what the "H.M.L. No." is. It's difficult to imagine a dealer having so many of this scarce variety, but the text appears to have been some sort of inventory control information.

I'm hoping someone can shed light on one or both of these items.
