The first place I'd look in a PS file is in the header comments,
specifically "%%Creator:". But DSC comments aren't strictly required
(although PS documents lacking them are called "nonconforming"), so
you may end up in the murky realm of "idiom recognition". Likewise if
the Creator comment is a person's name rather than an application's.

Often, yes.

For example, an EPS created on a PC with Corel Draw will contain this comment:

%%Creator: CorelDRAW 10

And a PDF produced with Acrobat Distille will contain this key:

/Producer (Acrobat Distiller 4.05 for Windows)

Thanks Tom.

I obtained a PDF from a client and when opening the file in Acrobat 6 Pro. the document properties do not list the application, just the PDF producer (Acrobat Distiller 5.0.5 for Macintosh).

Would you agree, based on the sample code below from the PDF, that the application used for creation was Illustrator 10?

Thanks so much for your very informative help!

Not necessarily. It might mean that whatever software created the PDF
included a file (a star logo) made in Illustrator.  

Aandi Inston

The application which created the PDF is Distiller 5.0.5 for Macintosh. The application which created the PostScript stream that was passed to Distiller was (probably) Illustrator. See Aandi's note above.

However, I would say based on the /Title and /Creator keys, that you've made a very good educated guess, and that the PDF was created by Illustrator-via-Distiller.
