Vintage geological specimen collection card with mounted rock and mineral samples

This type of educational specimen card was commonly produced from the late 19th through mid-20th century for teaching geology and mineralogy in schools, universities, and for amateur collectors. The specimens appear to include various sedimentary rocks, minerals, and possibly fossils or concretions, carefully labeled and mounted on a display card for study purposes. Such collections were popular during the golden age of natural history education when hands-on learning materials were essential classroom tools. These specimen cards are valued by collectors of scientific ephemera, vintage educational materials, and natural history enthusiasts who appreciate the intersection of science, education, and historical artifacts. The appeal lies in their aesthetic presentation, educational value, and connection to the history of scientific pedagogy. Collectors of geological specimens, vintage school materials, and cabinet of curiosities items find these pieces particularly desirable for their nostalgic charm and documentary significance.
