Am I allowed to ask about font IDs here?  

The top specimen
looks a lot like a face called Avant Garde (mid-late 1960s?), probably designed by Herb Lubalin for International Typeface Corp. If you can find an old ITC catalog, or the book reprinting the old typography journal called _U&lc_, you might find clues to the other two designs. Readability, schmeadability.

Waitaminnit...
Is that model Marilyn Chambers?

these
These are modern images, and look like the work of Show Studio to me

COOL!!!
Thanks Geo H! THIS is why I love this forum.
The model is actress Chloe Sevingy.
There might be more people out there wanting to ID fonts. I understand if P+A would not want the forum overrun with Graphic Design posts, so why don't we make this the offical "font ID and related" thread. Is that a good or bad idea? Dunno. But I do know I super appreciate the help, I've been scratching my head on these fonts for a couple of weeks now.

Thanks robert1960
Do you know if they have a site?

They Do..
They Do, but I can't find these images..
so.. they must be by someone else.
)I can see the name Jane How on one of them, she works for Show Studio, and lots of good international magazines)
you'll enjoy their site anyway !

Wow robert1960
I love that YSL campaign!
So understated, and I can't believe that was Gisele, didn't recognize her at all.

Not avant garde/ do a search...
Not avant garde/ do a search on Herb Lubalin Avant Garde...was created as the cover/font for the magazine.As an odd aside when I cannot date an object often a sticker or label on the object, will betray something in the font used that can quickly date an object...

Not quite
What you see may resemble some known font however... when I did this for an ad agency we started with a font that was about what we wanted for some graphic design, then we convert the type to outlines that we then edited in Adobe Illustrator.

Not Avant G.?
Sorry, Azure, I'm not following you. I had the impression that Lubalin designed a whole font (with a range of bold, medium, and light faces) based on his earlier logo design for the magazine called _Avant Garde_. No?
Meanwhile, you are spot on about typefaces as clues to the age of an artifact. Anachronisms are a dead giveaway. Somewhere (must find it) there's a diverting column on non-period typefaces used in movies (Helvetica on the Titanic's instrument panels in the eponymous film, for instance).
And don't get me started on the Helvetica documentary. Regards,

One last thought
and I'll shut up. Last spring I ran across quite a nice old pendulum clock (c. 1900) on the face of which someone had neatly and painstakingly applied "SETH THOMAS" in tiny 1970s-era rubdown letters -- in Helvetica! A transparent ruse? A gag?
Could a closer look at the type help date the labels on the Nelson ball clocks under scrutiny in another DA thread?

YES
you are correct, I agree... but what I was pointing out the first face shown on this thread is not avantgarde.I actually have a few of the old avantgarde mags...Type faces evoke a period like few things do.Funny about the Titanic!
