Mats Jonasson-style intaglio lead crystal wolf sculpture

This decorative sculpture features a clear glass or lead crystal plate with an irregular, jagged 'ice' border, consistent with the aesthetic of Swedish crystal makers like Mats Jonasson or Målerås. The central motif is a reverse-etched (intaglio) scene depicting five wolf pups, four of whom are positioned as if howling. The frosted white texture of the etching contrasts with the transparency of the surrounding material, creating a high-relief appearance when viewed from the front. The glass sits upon a dark, rectangular base that appears to be made of slate or a similar textured stone. The base bears the cursive text 'Heart and Soul' in a metallic white or silver tone. The craftsmanship suggests a late 20th-century origins, but without a visible company signature or original label, the exact manufacturer cannot be stated as a fact. The surface appears to be in well-maintained condition with no visible chips to the central glass or major flaking on the base. The piece utilizes light-bending properties to illuminate the pups, which is a common technique in European art glass of this style.

Based on the provided description and image, I have examined this intaglio art glass sculpture featuring a wolf motif. The piece exhibits characteristics typical of Swedish crystal, specifically the style popularized by artists at the Målerås glassworks. However, because I am viewing the item via a photograph, I cannot verify the presence of a signature or acid-etched numbering on the base of the glass, which is common for such pieces. I can see the material appears to be high-quality lead crystal with a distinct 'ice' edge, and the frosted intaglio etching of the five pups is rendered with significant detail. The slate-like base with the 'Heart and Soul' inscription suggests this may have been part of a giftware line or a thematic series. My value estimate is based on the assumption that this is a professional production from a known studio like Mats Jonasson; if physical inspection reveals it to be a generic or mass-produced 'in the style of' imitation without a maker's mark, the value would likely decrease to the $20–$40 range. Market demand for themed animal crystal remains stable among collectors, though value is heavily dictated by the specific animal subject and the size of the glass block. To confirm this attribution, a physical examination would be required to search for a miniature stylus signature or a labels footprint. I would also recommend checking the base for any manufacturer's marks or artist initials that may be obscured by the stone plinth. This estimate assumes the glass remains free of chips, as even minor flea bites to the faceted edges would significantly reduce its marketability.
