A small number of paintings are also thought to be his work, notably the "Pair of Lovers" in Gotha, the "Speyer Altarpiece" (divided among Gemäldegalerie, Berlin, the Städel, Frankfurt, and Augustiner Museum Freiburg, and the "Holy Family" (Nuremberg, Germanisches Nationalmuseum, since 2004). However, many scholars feel the Gotha "Lovers" and the "Speyer Altarpiece" cannot be by the same artist, and favour attributing only the "Lovers" to the Housebook Master. Others disagree, and attribute the engravings and the altarpiece to the same master.
