Vintage The Wizard of Oz Wood Mount Picture

The Wizard of Oz, Bert Lahr, Jack Haley, Judy Garland, Ray Bolger, 1939 sepia tone image mounted to plywood with a thick protective epoxy finish and black rounded edges. This piece is unique as I only found the image on poster online but could not find this exact image mounted and clear coated such as this particular one is. May be homemade/ handmade as my husband inherited it from a friend and we know it is 40+ yrs. Please let me know if you have questions and/or comments. Thanks!
