Epiphone described their DeLuxe model as follows in their 1934 catalog:

"On this and the following pages we shall try to tell you what has given EPIPHONE Masterbilt Guitars the qualities so much admired by those musicians who wrote the introductory page for us.  On the opposite page is illustrated that marvellous guitar, The De Luxe, which, by its performance has won a host of friends. First of all it is hand-made — top and back are carved, rasped, scraped and sanded to the shape and thickness which experience has taught us is most likely to reflect and intensify the vibrations of the strings and aid in producing that harp-like tone for which the De Luxe Model is noted.

Sides, back and neck are of first grade curly maple. The top is of finest spruce. With these materials as a starting point, we proceed as we might in building a fine violin. Each curve, each thickness at various predetermined points are carefully worked out_until the natural resonance of the top material is given full scope.The body is big and roomy — 20.25 inches long, and 16.375 inches wide at the widest part— the tone is round, full, sweet, and carrying as befits the “Choice of the Stars."

 

The oval fingerboard of genuine rosewood attaches to the curly maple neck which has triple center plies and a patented expansion truss for safety against warping. Neck and sides are finished to harmonize with the back which shows the flaming of the  the wood. A yellow sunburst on the top merges into the light brown of the edges, sides and back. The fingerboard is ornamented with genuine mother-of-pearl position marks and is edged with white Pyralin. Neck attaches at the fourteenth fret.

 

The edging of the top is white Pyralin containing an inner band of black and white block design, while the back is trimmed in black and white Pyralin. Gold plated individual tuning units, adjustable bridge, gold plated extension tail-piece, white pick-guard comprise other attractive features of the De Luxe Guitar. Made in Grand Auditorium size and Priced  at $275."
