Antique Spectrum Chart brings colored light spectra and wavelength bands in a scientific chart to a compact natural slate display made for a office, classroom, or studio.

The real stone surface adds subtle texture and an organic edge, giving this scientific illustration more presence than a standard paper print. It is a distinctive choice for physicists, teachers, and color lovers and for anyone building a collected, character-rich interior.

  • Printed on natural slate
  • Designed for tabletop display
  • Naturally varied edges and stone texture
