Pastel portrait consistent with Albert Schweitzer in a decorative gilt frame

This item is a bust-length portrait executed in what appears to be pastel or charcoal on paper. The subject depicted is an older male with thick, wavy white hair and a prominent white mustache, stylistically consistent with the appearance of Nobel Peace Prize laureate Albert Schweitzer. The artwork bears a signature at the bottom right reading 'Herman de Lijman', though this attribution remains a hypothesis subject to in-person expert verification. A small printed reference photograph is tucked into the frame, featuring text in German ('Was in Treue getan ist, ist nicht vergebens.') and the name 'Albert Schweitzer', providing unverified user context for the subject. The portrait is housed in a substantial, ornate gilt wood or composite frame featuring scrollwork, floral motifs, and a beaded inner border. The frame displays some chipping and wear to the gilded surface, consistent with the mid-to-late 20th century. The paper substrate shows a neutral tan tone with minor age-related discoloration. This identification relies on visual likeness and unverified text; physical inspection is necessary to determine if the signature and work are by the hand of the named artist.

I have examined the digital image of this bust-length pastel portrait, which displays a subject bearing a strong likeness to Albert Schweitzer. While the work bears a signature consistent with Herman de Lijman, I cannot verify the authorship or the medium’s stability through a photograph alone. From what I can see, the execution shows a high degree of technical skill in capturing the subject's features and character, and the paper substrate appears consistent with mid-20th-century materials. The ornate gilt frame adds significant decorative appeal, though I cannot determine if it is carved wood or a composite material without a physical inspection. The visible wear and chipping on the frame’s surface suggest a period piece rather than a modern reproduction. The estimated value of $400 - $800 is based on the assumption that the work is a period piece by the identified hand in a desirable decorative frame. Market demand for localized mid-century portraits varies; should the attribution to Herman de Lijman be found incorrect, or if the work is determined to be a later copy in the style of the artist, the value would likely decrease to a decorative range of $150 - $250. To provide a definitive valuation, an in-person examination by a specialist is required to confirm the medium, assess the paper's condition behind the glass, and verify the signature's integration into the pigment layer. Provenance documentation or a gallery label would also be necessary to solidify the work's history and support a higher market placement within the fine art category.
