If this is the UK company Viyella owned by Austin Reed ,their shirts do tend to have Logos if you can live with that.

The whole Viyella subject is a complicated one.

Viyella is obviously a cloth mixture of wool and cotton usually
and many manufacturers brand them as such  lands end, OC's for sure.

However there is a company in the UK called Viyella owned by Austin Reed which is i think the ones on e bay are.

Usually they have small collars and  have some sort of stag logo on the breast .

I have loads of UK Viyella shirts, new and vintage that are 80/20 mix and they don't itch me at all.  I find they are quality and last years without any change at all.   They do button down collars of various sizings, dependent on season, individual shirt.    As has been said, don't confuse the viyella cloth with the label.   Even the label isn't really the same one, it was bought out by Austin Reed when it was in trouble.   They do keep it as a separate line with some great items in a country look that has some Ivy crossover.

The shirts on eBay tend to be NOS from the original label and well worth picking up.   Although the pattern is a bit garish on that shirt, I love a more subtle Viyella button down in tattersal check which go excellently with the right wool jackets, jumpers etc.

The ones at Lands End are not the same.   I do like some Lands End shirts but they vary greatly in quality.

Indeed stiff collars and generic sizing. I have a handful (bought in one shot) and they're relegated to weekend cabin wear, lounging around the country comfort shirts; even at that they aren't great.

That A&F by Hathaway is my number one contender to pair with a grey shaggy shetland and a pair of grey tweed or flannels on a brisk day; 3/2 honey-caramel cord sack optional!

Just been browsing O'Connell's...  They keep on stocking Viyella, apparently made in the USA or Canada...  I've no problem with that at all, although I used to live a stones throw from the Via Gellia, after whom the company is named.  The John Smedley factory is close by.  But, in this thread, a logo is mentioned: slightly annoying I'm sure you'll agree.  A little tag also features, rather like that on the Grenfell jacket I once owned.  I removed that with a craft knife.  But the real issue is a jacket I spotted - not sold by O'Connell's I hasten to add - which is made in China.
Makes Smedley and Community Clothing look all the more desirable. 
Their shirts can, I suppose, look a bit ageing, as KingstonIan put it.  Boyer rather likes them, I think.
I only have a couple now but their 60s stuff is not uninteresting if not terribly Ivy League.  The 'Corker'.
