Albertus Pictor's frescoes are found in churches, mainly in the Mälar landscape. At the end of the 19th century, Hans Hildebrand discovered in medieval documents that Albertus Pictor was both a painter and an embroiderer. Albert signed some of the frescoes but not the embroideries. Scholars such as Agnes Branting, Andreas Lindblom and Agnes Geijer studied Albert's paintings, compared them to embroidery and attributed church embroidery to him. The attributed embroideries were re-studied by Inger Estham, PhD in art history, PhD in theology at Uppsala University and former head of the former textile unit at the Swedish National Heritage Board and the National History Museums. Inger Estham studied the embroideries attributed to Albert with slightly different eyes. She studied them from a historical perspective, such as who might have acquired, donated or worn them. She also looked at them from the perspective of textile technology. Albert was not the only pearl embroiderer in Sweden at the time. She also dealt with other pearl embroiderers who were contemporaries of Albert and who are known in sources. In her research, she also presented a previously unknown bead embroiderer in the context of textile research. When Inger Estham passed away in 2016, her work was in an incomplete manuscript draft. She bequeathed her research material to Mari-Louise Franzén.
