Princess 300 with RaRo Elite Imperial typeface

The "AR" foundry mark is a shorthand for Albert Rodrian, one half of RaRo. If you ever see an R inside an octagon that's the mark for the other half, Alfred Ransmayer.

The "84" on the foundry mark is typical of RaRo's 12 pitch Elite Imperial which can be found with a sample at: https://typecast.munk.org/2023/02/04/1961-adler-typewriter-type-font-styles/

If you put a ruler up to your type, you should find that there are 12 characters per inch.

Aortic dissection typically presents acutely with sudden, severe tearing chest or back pain, often described as lancinating in quality. [5-6] Approximately 50% of patients with thoracic aortic aneurysm may progress to dissection without timely intervention. [5] In contrast, thoracic aortic aneurysm is usually asymptomatic and discovered incidentally during physical examination or imaging for other indications. [5]
