Possible Farley Gift Sheet Stamps On 1934 Cover?

Hi, I'm new to this forum but have been collecting U.S. postal history for 40 years. I posted this on the introduction page and it was suggested that I do so here. My question is somewhat straightforward. Is it possible that the stamps on this cover are from the Farley Gift Sheets? (The ones that were given to FDR, Ickes, etc. by Farley?) The postmark is clearly from October of 1934, long before the Farley imperfs were issued in March, 1935. The receiving postmark is also from 1934 in Oregon. It clearly looks philatelic but that may not mean much.... As I indicated in my initial post, the recipient was a collector and postal employee in Albany. I did further digging and discovered that the recipient's sister was in Hawaii at the very time it was postmarked and therefore it's possible that she sent the item to her brother. I would be interested in anyone's thoughts on the matter. For starters, does anyone know of any Gift Sheet Stamps that have been identified on covers? I hope this has not been somehow created to look like it came from the gift sheets but I don't really know. If it's faked somehow, it appears to be quite well done. Thanks

Here is the reverse side of the cover....

The margins are trimmed very tight. I would examine it very closely for perforation remnants.

Hi, thanks. I looked at that but don't see anything. In fact, I see a green line on the Yosemite on nearly all of the right side of the stamp. Meaning, at least for that stamp, it seems highly unlikely that there were perfs there that were cut. At first I thought maybe it was somehow an early release of the souvenir sheet stamp but then the green line shouldn't extend the entire length of the stamp...only in the design area....

In the perforated version, the green line is a natural straight edge from cutting the press sheets into panes for retail sale. I would be overlay fully perforated versions to see if your stamps fall fully within the perforated area.

Thank you. I actually took another look at the bottom of the Yosemite and I can indeed make out the tiniest little pattern of divets in the paper...meaning it does look like the perfs were cut. And of course if one was cut they were all cut presumably. It does make for a nice little item though and to go further down the trivia hole, the date that it was postmarked in Hawaii was the last day that the volcano was erupting in the Park. (It had been dormant for at least several years prior....) And it's still entirely possible that the recipient's sister sent it as she stayed at the Volcano House. All cool stuff but the stamps were altered. Thanks! You helped me solve this mini mystery!

As an aside, the Volcano House post office changed to Hawaii National Park in 1929. Here is the Postal Bulletin announcement in issue #14920 of Feb 15, 1929. (Jim Forte has this change as 1928)
