Here’s a link to the dvd I have, just checked the run time and it’s 7 hours and 20 minutes.

Great book about the history of that song, and how a death during a botched robbery influenced and inspired the dark message of the song:

These shots are definetly from Dallas on June 6, 1975. Photos from that show are not really common. It would be nice to see them a bit clearer but appreciate the share anyway.
BTW most of that show has been officially available on the "Elvis Aron Presley" boxset since 1980. It has been re-released in enhanced sound on the SONY Legacy twofer release of "Today". You might want to check this out for your mom:

Although one of the later shows it is quite fun to listen to as Elvis in high spirits and delivers a quite entertaining show.
You should check this guy out - while he's not Elvis, he might scratch that itch you've got:
Try amazon with the 68' comeback special 50th anniversary https://www.amazon.com/-/es/Elvis-Presley/dp/B07HBG8YJN Or the DVD sets https://www.amazon.com/Elvis-Presley/dp/B000G7PO6W/ref=mp_s_a_1_2?crid=283P3JQ7M2G2Y&keywords=elvis+presley+68+comeback+special&qid=1638920532&sprefix=elvis+presley+68%2Caps%2C484&sr=8-2
I recommend Amazon for having quite safe transactions and stuff if you are not that satisfied with the product
I'll second this, and also the physical version of the new Back in Nashville set coming out later this November should have some retrospective liner notes as well since it includes the material from those sessions.

If you don't have it, used paperback versions of Ernst Jorgensen's Elvis Presley: A Life in Music aren't TOO hard to find at reasonable prices if you shop around Amazon/eBay/etc. Hardcover, forget about it.

This is a great one. If you haven't read the Guralnick books, make time to do so at some point. They are TEDIOUS but worth it.
The book I linked above is probably my second fave behind the Guralnick books.
If I'm not mistaken, almost all of his movies are available for rent/stream on Amazon video.
If you'd like to own it, you can also get the DVD. Some amazing backstage footage leading up to this show.
The picture framed is about $40. The one you have is a much nicer frame though. Unless those are authentic signatures, you're probably looking at about $75-$90. That being said, it's a wonderful piece.
Edit: Bumped up the price a bit.
If not the Doug Church Album, Kingtinued https://www.amazon.com/dp/B00000JLT7/ref=cm_sw_r_cp_api_i_DbC9AbV3B6JRW
It might be the Ronnie McDowell album Elvis: A Tribute To The King

One of my favorites because it's from a very different perspective than most Elvis books "My Life with Elvis: Becky Yancey" - Becky was the head secretary in the office at Graceland. I read it when I was a kid. Lots of interesting anecdotes while she worked at Graceland everyday as a regular 9 to 5 full time job for so many years. Vernon was always a nervous wreck with money. Haven't read it in decades but one thing I remember, she would open up and organize all his fan mail. One day (1960's) she opened up a package and found a dead parrot with a letter from the owner begging that her beloved pet parrot be buried on the grounds of Graceland. They obliged her. http://www.amazon.com/My-Life-Elvis-Becky-Yancey/dp/0312558341
