Framed oil painting in the late 19th-century genre style

This interior genre scene, likely executed in oil on canvas or panel, depicts a man in historical Renaissance-style attire. He is seated at a tavern table, holding a decorated ceramic stein or tankard. The figure wears a dark doublet with yellow puff sleeves, matching yellow hose, and a soft cap, appearing to reflect the 16th-century 'Landsknecht' or 'Cavalier' aesthetic popular in 19th-century romanticized genre painting. In the lower-left corner, the work bears a visible signature in red pigment reading 'K. STREET', which the owner has also noted; however, this attribution is unverified and requires in-person expert authentication to confirm the artist's identity. The composition features a muted, earthy palette of ochre, brown, and gold, with skillful handling of light and shadow on the figure's face and clothing. The piece is housed in an ornate, deep-profile gilded wooden frame with repeating carved 'crescent' or 'scallop' motifs. While the painting appears to be in stable condition, there is a slight yellowish cast to the varnish, consistent with age-related oxidation. The frame shows minor surface wear but remains intact. The overall craftsmanship is consistent with European academic traditions of the late 1800s.

I have examined the digital image provided of this interior genre scene and its ornate frame. Based on what I can see, the painting exhibits characteristics of late 19th-century academic European works, featuring a romanticized 'Cavalier' or 'Landsknecht' theme. Per user submission, the piece bears a signature in red pigment reading 'K. STREET' in the lower-left corner. I am treating this attribution as a hypothesis only, as I cannot determine from a photo if the signature is contemporary with the paint layer or a later addition. The estimate assumes the work is an authentic example by an artist of this name from the period. If authenticated, the piece would likely sell in the $400 - $800 range at auction, given the popularity of this subject matter and the quality of the frame. The value is bolstered by the skillful light handling but tempered by age-related varnish oxidation. However, should the work be determined to be a later copy, a 20th-century reproduction, or by an unidentified follower 'in the style of' the period, the market value would likely decrease to $100 - $250, primarily reflecting its decorative appeal. To confirm the identity of the artist and the age of the materials, I would need a physical inspection to check for canvas age, pigment composition, and UV fluorescence of the signature. Provenance documentation or a entries in a catalog raisonné would also be required to support the attribution. General market demand for 19th-century genre paintings remains stable for high-quality decorative pieces, though values have softened compared to late 20th-century peaks.
