So interesting. Thank you so much for this!
I have no doubt KL could found this or another photo of this bag, or the bag caught his eye in the 1970s in Paris. Unlike other designers KL was very observant of things outside his own work (prob working for Chloe at that time). It may have been a novelty in the 1970s and KL brought it back and publicised the hell out if it, perhaps it suited him and the House to credit him. Perhaps he added the leather thread through the chain and hence a new bag design.
The jewellery (earrings) also looks like a foretelling of styles to come, those earrings ware very remnant of 1980s Victoire de Castellane styles who only worked with KL in 1984, but
these must have been still Robert Goossens at that time.
I have a bag, a forerunner of the Mademoiselle and a suit from the early 1970s. When the Just Mademoiselle came out in 2011(?) no one talked of its past. No one expects people to be interested in the history of fashion, because fashion has always relied on pretending everything must be bought new and part of the zeitgeist. Mine has leather-woven chain handles, the 2011 one does not. Basically it is still the same bag.
KL hated people thinking he lived in the past, he was phobic about it, prob because he was worried he would end-up like his arch rival YSL, insular and from KL mumbled living off past glories.
I find things don't match-up re Guccis official history and research. I found a suspiciously similar 'Flora' motif used as embroidery on a 1940s bag presented through this forum by a member (who then sold the bag to the
Gucci Museum - using it to create new bags without a word about the history). Officially, and more famously, the story was Rudolfo Gucci had the idea for Flora through wanting to present a silk scarf to Grace Kelly in 1966. So much more flattering to a Princess to say it was entirely inspired by her beauty upon meeting her and get the artist Accornero to work on the design. Nothing gets in the way of a good story. Head of Handbags at Chisties partnered with Gucci (they are affiliated through parent company) has recently stated the GG-print came out in late 1960s, when actually it was devised by Paolo Gucci in the mid-60s but who used the luggage print on clothes in 1969 as a PR stunt that went whatever that time's version of 'gone viral'.
Chanel didn't invent the LBD either, women had already wearing LBDs for everything by 1926 - it was a cultural phenomenon and didn't belong to one person, but she did know how to market Chanel/herself. KL did too. We shouldn't be surprised. The quilting didn't come from jockey wear (silks) either as often reported, it came from paddock jackets (very few sources get that right, so glad PB has) she stole the collar type for some jackets from silks though, the tweed from trad. hacking jackets. She took the large bows from the original 'Flapper girls'. And yet she didn't believe in 'costume'
Nothing gets in the way of a good (fashion) story, so long as it sells.
