Art Explosion Gold, with 125,000 clip arts and images. They're all public domain, so free to use for whatever projects without having to worry about copyright. Lots of alphabet letters and ornamental borders and silouettes, etc. The index book is printed in black and white, but all of the graphics are colour. The set says Macintosh only, I couldn't get them to open on a Windows computer but there might be a way if you are technically savvy.
