Authentic Wegner Papa Bear Chair??  

Additional Images
Here are a few additional images of the chair.

And just a couple more images
Shown below is the area that looks like it may have once had the sticker.

I don't think that seat cushion
is original. I do think the chair looks authentic.
I would bet that someone long ago didn't like the feel of the thinner foam cushion that was original to the chair, so they had the chair reupholstered and asked the upholsterer to stick a sprung cushion in there. He went with the pre-formed cushions that are standard for a conventional armchair but that are much too deep for a Papa Bear, hence that overhang in front.
Alternative version: upholstery fabric is original and somehow the guy who made the sprung cushion got fabric to match. I only offer this theory because it seems unlikely that the same person who would put that seat cushion on the chair would also do such a nice job on the rest of it, but what do I know.
Fun video below of the chair being upholstered, which apparently only takes ten minutes. (har har har)

Thank you for the very neat...
Thank you for the very neat video! The video shows one of the workers putting some sort of burlap type materials underneath the blue upholstery. My chair has a similar material as seen in the image below...

Strictly speculation
But I like your first version, spanky, with one twist: the person who owned the chair was an upholsterer himself. Then the contrast of the cushion and the perfect workmanship makes sense.
Is it odd to anyone else that it is upholstered in a twill? Seems like it would be a hopsack?

It looks like a wool gabardine type
fabric to me. This is a fabric that was used back then---dunno if it was original to Papa Bear chairs but I've seen it on a other old Danish pieces.

Thank you all for your help! I'm super excited by this find. Picked it up at a yard sale this weekend. As much as I love mid-century modern, this piece just doesn't quite fit in with the rest of my room. That, and I've run out of space! Any ideas of how to go about selling it? Ebay? Craigslist? How in the world do people ship such large items?

just tell us
how much did you pick it up for?

A
gentleman never tells. 🙂 Let's just say that bargains are still out there to be found.

oh, pshaw!
You're among friends. And you will give hope to others if you spill the beans.

Also,
don't get rid of it right away. There was a time when I thought Papa Bear chairs looked odd and weren't something I wanted in my place ever. But they have grown a lot on me and I am glad I never had the chance to sell one back when I wasn't so in love with them.
This has happened with a number of things for me---both stuff I held on to that I wasn't sure I liked and then later I grew to love it, and stuff I got rid of and later really regretted.
So, think about it for awhile before you do anything rash. That's all I'm saying.

Thanks all!
I'll think about it before selling, but really I'd have to re-do the rest of the living room for it to match. Plus, there is the issue of having room for it, which my little "chair collection" precludes. This, coupled with an upcoming move of residence which could definitely be assisted by funds from selling the chair, makes the prospect extremely tempting.
One more question, do people ship such large items? Seems like there would be a service for this, but it also seems a bit of a hassle (not to mention expensive).

People use freight services
and also Greyhound (a lot cheaper), but I don't think I'd put a Papa Bear chair on a bus.
