File:The crest of Phi Delta, Alpha Pi chapter version.png

Summary
The national crest appears to be versioned by chapter, with the chapter name inset, in smaller letters. This hand-drawn crest is the only one I could find for the fraternity, after searching multiple yearbooks for most of its schools. The Columbia yearbooks may have a better version, but were inaccessible to me. I cropped the image, color corrected, and have reduced it by 70% from the original screen capture.
