The Goetia, or Lemegeton Clavicula (The Lesser Key of Solomon the King, Clavicula Salomonis Regis), is part of a pseudoepigraphical work, i.e. claiming to be by someone (Solomon) but almost certainly nothing to do with Solomon. It probably dates from the 17th century, although it is based on texts at least as old as the 14th century. S. L. Mathers transcribed it into a more modern English, and copied (I think) the illstrations. There are 72 different demons described, each with one or sometimes two seals. I have scanned the seals at 1200dpi, because I could not find any acceptable scans on the Web. The designs of the seals are long out of copyright.
For the extracts I have used a combination of two versions that you can easily find online, and I have compared them to the 1995 edition edited by Hymenaeus Beta and published by Samuel Weiser; the text was published in the US in 1916, and is out of copyright, although that edition was probably not authorised by Crowley or Mathers. Since Crowley attributed the text to Mathers, however, who died in 1918, it is all out of copyright.
The sizes given for the seals are approximate: they do vary very slightly, since they were hand-made.
Resurge has made some free Photoshop Brushes (here is the second pack) from the 700-pixel versions of the seals of the 72 fallen angels.
