Hemispherical glass shade with a globe-style terrestrial map

This object is a hemispherical glass shade, consistent with the user's description of a lampshade, featuring a printed or applied terrestrial map of Earth. The primary colors include a deep matte blue for the oceans and various shades of green and yellow representing landmasses, such as North America, which is clearly visible. The glass appears to have a frosted or satin finish, providing a diffused texture. At the apex of the dome, there is a circular aperture, which is standard for mounting to a lighting fixture. The condition of the shade appears fair to good from this angle, though there are visible surface scuffs, faint scratches, and areas of dust accumulation across the blue oceanic sections. The map detail shows some cloud-like white patterns, suggesting a satellite-view aesthetic. No maker's marks, signatures, or branding are visible in the provided image, so any specific manufacturer attribution remains a hypothesis subject to physical examination. The owner identifies this as a glass lampshade, which matches its geometry and central hole. Its design is stylistically consistent with late 20th to early 21st-century decorative home lighting or educational-themed decor.

Based on the provided image, I have examined this hemispherical glass lampshade featuring a terrestrial map design. The object appears to be a mass-produced decorative lighting accessory, likely dating from the late 20th to early 21st century. The satellite-style imagery and the frosted texture of the glass suggest a contemporary manufacturing process. The presence of a standard central aperture supports the owner's identification of the piece as a lampshade. From what I can see, the condition displays signs of wear, including surface scuffs and dust, which are typical for utilitarian glass objects but do detract from the aesthetic appeal. I cannot verify the specific manufacturer or the exact method of graphic application from a photo; a physical inspection would be required to determine if the map is a high-quality glass transfer or a simpler printed film. The value estimate of $40 to $85 reflects the current market for educational-themed home decor. This range assumes the item is an unattributed contemporary piece in fair condition. Items of this nature generally sell based on their decorative utility rather than brand pedigree. If this were to be identified as a limited-edition piece from a high-end lighting firm, the value could increase slightly; conversely, if the surface damage is more significant than perceived—such as deep scratches or heat-related stress fractures—the value would likely fall below $20. To establish a more precise valuation, one would need to inspect for etched maker's marks around the fitter rim and confirm the structural integrity of the glass.
