Vintage Ben Seibel for Jenfred Ware Brass Triangular Bookends

Stone cold classic Ben Seibel brass bookends - these are what got me hooked on mid-century style in the first place.

Designed by Ben Seibel, produced by Jenfred and distributed through Raymor.
(Coincidentally, I am selling a yellow glass gin decanter which was also sold through Raymor and bears the original sticker).

This set is from the 1960's and represents one of his most famous designs.

Each bookend measures 6 1/4"high x 5"wide x 4 3/4"deep. 

Both are in good condition, with some wear on the book 'slides' and the felt underside.
Each bookend is a missing screw on the underside, but it doesn't seem to effect stability etc.
The brass shows signs of age, which is exactly what I adore - I wouldn't polish these for the world.
