Ulrich Stoll's sister, Herta Burkhardt, fulfilled his last wish and safeguarded his complete collection, about 250 paintings, many diaries, and notebooks. Ulrich Stoll himself was convinced that the complexity of his works would not be appreciated until the future. His semester reports and the diploma with the grade “excellent” have also been also preserved.

In 2005, Herta, who was by then already 80 years old, passed the legacy of her brother to her son Ulrich Burkhardt. Thanks to his efforts and research, the collection is now almost complete. The Oeuvre of Ulrich Stoll contains around 400 works including all drafts and sketches, a major part of it in family ownership. Additionally, the collection contains diaries, sketchbooks, a personal album with photos from his time at the Werkschule Trier, as well as the correspondence during war times, his war time captivity and the “Trier-Letters” from 1947 until his early death in 1952.

On the occasion of an Ulrich-Stoll exhibition in the year 1993 Ulrich Stoll's friend Jakob Schwarzkopf presented a painting that had never been completed. Ulrich Stoll had crumpled it up during his time at university and had thrown it into the waste basket, because it seemed not to be good enough to him. Jakob Schwarzkopf took the picture (Title: Bunte Pferde), framed it and kept it as a special memory until his death in 2001. Schwarzkopf had always dreamed of reaching comparable skills one day. Stoll's fellow students always considered him to be the most talented and multisided versatile of them.

The brochure of the former director of the Werkschule Prof. Heinrich Diekmann (“Trierer Werkschule – Schule für Kunst und Handwerk”) shows the draft of a /for a poster for the city of Trier from Ulrich Stoll. This work is also included in the collection.
