Mixed-media architectural study on paper with unverified attribution tags

This item is an original artwork depicting an architectural facade against a bicolored background of deep brown and navy blue. The medium appears consistent with a combination of pastel, colored pencil, or watercolor on a heavy off-white paper or cardstock. The composition features a grey building structure with an arched window and a decorative balustrade. A small yellow adhesive note is stuck to the brown field on the left. In the lower left corner, a paper label is attached bearing handwritten text that reads: 'ROGER MILLET', 'No 1 Set 2', '5" x 8 - 10"', and 'South Elevation House'. This label serves as an unverified user-attributed identification to Roger Millet, but as this is a movable tag on a work without an integrated signature, the attribution remains a hypothesis subject to physical inspection. The work shows signs of handling consistent with a production sketch or student study, with slight unevenness in the pigment application and minor surface wear at the edges. No date is directly readable, though the style is consistent with late 20th-century architectural illustration. The lack of an integrated signature requires hedging regarding the artist's identity.

Based on the digital images provided, I have examined this mixed-media architectural study. The work features a composition consistent with mid-to-late 20th-century production sketches, utilizing what appears to be pastel or charcoal on heavy paper. While the item bears a label attributing the work to Roger Millet, I must treat this as a hypothesis rather than a fact; the label is a movable tag and not an integrated signature, which introduces significant uncertainty regarding authorship. A physical inspection would be required to determine if the pigment application and paper age align with the period or the specific techniques associated with the attributed designer. My estimate reflects the market value for an architectural study of this quality assuming the Roger Millet attribution is correct. Architectural illustrations of this type are collected for their aesthetic and historical utility in design, frequently selling in the $150 to $400 range at regional auctions. However, the value is heavily dependent on authentication. Without documented provenance or an in-person expert review to link this piece to the Millet studio, the work would likely be valued as an unattributed student or architectural study, which typically commands a lower range of $50 to $100. Factors such as the visible surface wear and the non-permanent method of identification suggest this was a working document rather than a finished gallery piece. To increase confidence in this valuation, I recommend seeking provenance documentation or comparing the drafting style to known examples in a physical archive.
