* Notes about these prices:
- They are currently in beta mode, meaning that they should not be relied upon yet as a source of truth and could change frequently. Please notify PSG if you come across values that do not make sense.
- They are not based on catalogue values but on current dealer and auction listings. The reason for this is that catalogues tend to over-value stamps.
- They are average prices and might not be fully accurate. The actual value of your stamp may be slightly above or below the listed value, depending on the overall condition of your stamp.
Canadian scientists have helped to banish the darkness, to feed people better, to view the smallest objects, and to cure once fatal diseases. The electron microscope generates a picture by using a beam of electrons - rather than light - to illuminate an object. Under the supervision of Dr. Eli Burton at the University of Toronto, James Hiller and Albert Prebus developed the first practical model, in 1938. Electron microscopes can magnify images up to one million time their true size. These stamps, designed by Roger Hill of Toronto, mark the end of the three-year stamp series on Canadian Innovations in Science and Technology. The scientific achievements being honoured have been accurately rendered in a pleasing and precise illustrative style. Like the previous two issues which focussed on the themes of Transportation and Communications, this year's stamp designs features notes, drawings and diagrams on the development of each innovation on their backgrounds.
