That's what I wrote then and I still think it's true:
The big hair and fashion clearly date this deck but I was young in the Eighties so that doesn’t irritate me. IMO the Cosmic is a great deck, very intelligent and a reflection of the fact that movies and movie stars interact with our unconscious mind powerfully.
I’ve heard people say that the “celeb faces” are just a gimmick. I disagree. I think the artist saw stars like Garbo, Berman or Bogart as 20th century versions of archetypes, not "celebs". He also used paintings (Bougereau) and ballet scenes for the deck. It’s full of cultural hints and suggestions.
There are some people on the Internet who think Leonardo di Caprio or others are depicted in the deck. As his career only started when the deck was already printed, that's impossible.
The artist is German. From what I read about him, he was not "obsessed with celebrities" but with spiritual search when he painted his deck, and continued his spiritual search afterwards. I think he worked very closely from photographs and took his inspiration from many different sources. I totally agree with him that Greta Garbo is an icon and archetype of the 20th century.
I never read anywhere about the ballet as inspiration for his tarot art although many of his cards show obvious poses and motifs from at least one famous ballet (and probably more - I simply don't know enough about ballet to find more).
Maybe people will appreciate this very special deck more when they see how wide and far the artist threw his net to find inspiration for his archetypes. I certainly did, and I've been hunting down inspirations for his cards for years.
I have distributed my findings: first the majors and the minor suits.
Let's start with the obvious.
The Emperor.

Lösche grew up in Aachen/Aix la Chapelle, and he must have known the golden bust of Charlemagne from childhood. It's in the treasury of the splendid cathedral, and in Aachen, Charlemagne is everywhere. Aachen was the capital of his empire, after all.
Charlemagne is an obvious choice for the Emperor, and for an Aachen native, even more so. You can't go anywhere in Aachen without seeing Charlemagne's image, it's everywhere.
If the inspiration for the Emperor was medieval, his Temperance is probably modelled on 20th century illustrator Warwick Goble's works.
What a beautiful, harmonious image for Temperance. And here is Warwick Goble:
It is possible that the Star card was inspired by Goble, too.
And another Goble illustration:

Mata Hari's poses from the early 20th century also remind me both of Temperance and of Warwick Goble.
Orientalism at its most tantalizing and "exotic"... and as mixture of East and West actually an interesting metaphor for Temperance.
Let's move to Justice.
There are two actresses whose pictures may have inspired this wonderful card with the piercing look.
Billie Burke in her iconci role as Glinda, witch of the North, who sets things to rights again.
Jeanette MacDonald, singing La Traviata in San Francisco, also reminds me of the card, somehow. I'm pretty sure that Glinda is the source, though.
Strength.
I'm inclined to think that this original and interesting concept of Strength is one of the best cards of the deck, and the lady depicted looks to me very much like Hedy Lamarr, the gorgeous, daring and highly intelligent Austrian actress.
It was written somewhere on the Internet that Daryl Hannah, a star of the 80s when the deck was made, was the inspiration. I don't know. I didn't yet find an exact image.

The hair is similar, but the facial expression - Lamarr all the way, imo.
The Lovers.
- lovers.jpg (26.51 KiB) Viewed 2607 times
I'm pretty sure that the inspiration for this card came from the movie Dirty Dancing.
Then the tantalizing question - who is the High Priestess?
Doesn't she look like young Greta Garbo?
Here is Greta Garbo playing Mata Hari:

What do you think? It's her face, isn't it? And who could better personify the HIgh Priestess than Garbo?
and it's probably right... although I couldn't find the exact picture. 
I remember trying to read with the deck and giving up after a while because (as a complete Tarot novice) I didn't know anything about the system and symbols. The cards were beautiful, but I couldn't make sense of them.
