I do recognise the scarf and wrote down a different name and date - 1937 SELLERIE - I too did not record the provenance of my info, probably a web site for which the link is long broken anyway
The early scarves were produced were produced over long periods, sometime over a decade, they were not pegged to a particular collection as they are now, so 1930s - 1940s seems good to me , I dont get hung up on EXACT dates for the early ones
I honestly dont know which name is correct - the only correct answer would have to come from H itself - I would go with their moniker no matter how many sites have otherwise
As to the fabric ... dunno .. I own several, they have a unique feel, they are all blends IMHO, could be silk,cotton, linen, wool in there , the funny cloth ones were NOT produced using the same blend/unusual fabric, also there were trade name blends Vyella (sp?) used by H, but dont know if this is one of them , you would need a CSI to do a DNA analysis to know for certain LOL
