The "board house" logo used on some of the PCBs for Apple 1 main boards and Cassette Interface boards.
Since the Apple 1 didn't actually HAVE a serial number (although some were added by retailers like the Byte Shop), it becomes somewhat of a guessing-game to try and determine where a particular Apple 1 sits in the (basically two) production-runs. And one of the things that helps determine that is the presence or absence of an NTI logo on the board.

Dang someone beat me to the joke.
That's kind of interesting. Because the NTI boards were the SECOND "run" of PCBs, and thus SHOULD be LESS rare.
For example, my Apple 1 does NOT have an NTI logo on the main board, but DOES have one on the Cassette Interface board, and it has a hand-written "serial no." of "1-0064" written in Sharpie on the back of the main board. This is true of other Apple 1 samples, too.
Here's the place to learn all about the "known" Apple 1 computers still in existence. Mine isn't listed, because I've never gotten around to sending the museum's curator pictures and stuff, but we have had some discussions about the "vintage" of my Apple 1:

I'd recognize that Apple ][ keyboard anywhere. But it's not surprising that connects directly to the old motherboard, the same way it connected to the new one. I was going to buy an Apple 1 kit but it didn't come with a keyboard and I had no idea how to retrofit one. So I bought a SOL-20 kit instead. Oops.
I did some research and it appears the "pre-NTI" boards were an earlier production run, they switched to NTI as the manufacturer of their printed circuit boards at some point. I put together a picture showing the NTI board on top, and the pre-NTI on the bottom. I believe these boards are basically the same color of green but the bottom pic is overexposed due to use of a flash. You can see the NTI logo inside a diamond centered under the Apple Computer 1 label. That logo is actually etched in the board, it's the same metal as the circuit traces. It's common practice for manufacturers to add their logo on the PCB like this. If you watch the video, this Apple 1 does not have the NTI logo etched in the board, so I have no idea what they meant when they claim it includes the "rare NTI sign." I think they meant just the opposite, that it is rare because it does
not have the NTI sign.

Exactly!
The NTI logo on the mainboard signifies a "second production run" board. Somehow, the "lore" surrounding the NTI logo has gotten mangled. The earlier Apple 1 boards, like mine, do NOT have an NTI logo. Mine has an NTI logo on the Cassette Interface; but not on the mainboard. I think all of the Cassette Boards have NTI logos.
This is the SECOND time I have seen that (purposeful?) mistake regarding the "rare" NTI logo, BTW. The first time was on that "Celebration" Apple 1.

I'm assuming that Woz soldered every one of these personally. That would be a pretty cool bit of memorabilia.
Sorry, but no.
I believe it was Daniel Kottke, Wendell Sanders (maybe), and maybe Randy Wigginton that built the Apple 1 boards.
Woz no doubt built a few for verification and modification purposes; but it was mostly NOT him.

Woz are secretly soldering more of these somewhere....
Sorry, no.
But if you can find the LANDFILL that Apple DUMPED a BUNCH of these in back in 1978 or so...
Woz told me in 1978 to "hang on to yours", because EVEN THEN, he estimated that there were only about "50 or so" that had NOT been landfilled.
So I did...
I have an original, one-owner Apple 1. It has become my "retirement plan". It may be the only one-owner Apple 1 still in existence!
Anyone interested? Save us both some Auction fees???

Yeah, and the Mona Lisa is just some dumb old painting...
