This is a beautiful box that I have had for years. I believe the initials are E.G.E.B. and it appears to be from the Art Deco period. There is a slight split running through the initials across the lid that I was told can be easily fixed. Does not show up well - see pictures 3 and 4. I didn't bother as I love the box and the age. the inside is deep blue velvet in perfect condition and on the bottom is marked "Xmas 1912". It's wonderful, lid measures 10 1/4 x 6 inches and stands 4 1/2 inches tall. No key I am afraid.
