Watercolor illustration depicting a mermaid, signed and titled (unauthenticated)

This piece is a matted watercolor painting or fine art print featuring a figurative depiction of a mermaid cradling a child or small figure, rendered in muted natural tones with distinct green hues for the tail and brown tones for the hair. The artwork is presented inside a protective plastic sleeve with a cream-colored mat border featuring a thin gold-toned inner line. Several handwritten inscriptions and markings are visible directly on the paper around the central image. To the upper left, handwritten text reads "'URSULA'" and "Sea Maiden" alongside the notation "# 22". At the bottom left, text reads "Sea Foot" along with another notation "# 2". An embossed circular stamp or seal is centrally placed near the bottom containing the letters "ECR", accompanied by a hand-drawn signature that appears to be in pencil or ink. A yellow thrift store price tag with a barcode is affixed to the lower right corner of the protective plastic, displaying the price 4.99. The physical condition appears clean and well-preserved within its packaging, though the artwork itself remains unauthenticated and its exact age, medium purity, and authorship cannot be verified from the image alone. The identification rests purely on the observed visual characteristics, legible handwritten titles, embossed stamp, and signature markings visible in the photograph.

Based on what I can see in the photograph, this matted watercolor illustration features a figurative mermaid motif with handwritten annotations, an embossed seal, and a signature. I can't verify from a photo whether the artwork is an autograph watercolor painting by a notable creator or a fine art print reproduction, and I cannot evaluate the medium purity or exact age without physical handling. The estimate of $100-$300 assumes that the work is a period-appropriate watercolor by the hand implied by the markings. General market demand for minor figurative and fantasy-themed watercolor works of this scale tends to be modest, appealing primarily to niche collectors of mermaid or illustrative art. If physical inspection reveals the piece to be a modern reproduction, offset print, or a copy 'in the style of', the value would drop significantly, likely falling into the $20-$50 range typical of decorative thrift finds. To establish a clearer valuation and explore potential authorship, I would need physical inspection to examine the paper stock, pigment behavior, and signature consistency up close, alongside professional provenance research and consultation with a paper conservation or illustration art specialist.
