It looks like a university Diploma. Here's some description:
- Font used is this old English font used on most university diplomas
- It states: "This is to certify [John Doe] has successfully completed all prescribed requirements and is hereby designated as Project Management Professional"
- Then you have the date of the validity of that certification (3 years)
- There is a fancy stamp on the left of the diploma.
- There is the PMI logo at the bottom right
- It is signed by the CEO and the Chairman of the Board of Directors.
You can frame it and be proud of what you've earned!
