My husband found in a relatives basement small yellow and blue boxes full of Ektachrome transperency slides made by Graflex of Rochester, NY.
Each of the boxes has the name of a story, with a number and there is also a slide viewer. Can you tell me about the history of these slides?
I woul also like to know if they have any value and if there are any collectors or market for them. Thank you very much, Irene
