Floral Still Life Oil Painting signed 'Kostka'

This framed artwork is an oil painting on canvas depicting a lush floral still life arrangement. The composition features a dense bouquet of flowers in shades of pink, red, white, and soft blue, housed within a simple round vase resting on a flat surface with a few scattered petals nearby. The background is a soft, muted mauve and lavender gradient. The paint application exhibits noticeable impasto technique, particularly on the flower petals, giving the arrangement a textured, three-dimensional quality. At the lower left corner, the painting bears a visible signature reading 'Kostka'. The artwork is housed in a dark brown wooden frame with mitered corners, complemented by an inner linen-textured fabric liner. The physical condition appears generally stable, though the item is unauthenticated and presented without provenance documents. The framing and stylistic elements are consistent with mid-to-late 20th-century decorative art production. The attribution in the name rests entirely on the legible signature observed at the lower left of the canvas surface.

Based on what I can see in the photograph, this framed oil painting features a lush floral still life arrangement characterized by a textured impasto technique and bears a signature reading 'Kostka' at the lower left. I must emphasize that a signature alone does not establish authorship as a matter of established fact. I can't verify the exact age, medium consistency, or canvas composition from a photo, and physical inspection by a qualified paintings conservator would be needed to confirm material details. The appraisal value range of $300 to $500 assumes the work is by the referenced artist 'Kostka'. This estimate reflects general market conditions and moderate consumer demand for mid-to-late 20th-century decorative floral still life paintings of this scale and execution. If the item were to turn out to be a reproduction, a copy, or a decorative work 'in the style of' rather than an autograph piece, the value would decrease significantly, likely falling into the $75 to $150 range as uncredited decorative art. To support the assumed attribution and potentially elevate market confidence, one would need formal provenance documentation, historical exhibition records, and an in-person evaluation by a recognized fine art specialist.
