2 Antique German Encyclopedia Books 3rd Edition Brockhaus Illustrated Covers Off

I am hoping someone will purchase to repair. Both of the bindings are completely off of both books. The more I handled them the worse they got! Ugh. But anyway, these are fantastic antique encyclopedias  form the Brockhause Kleines Conversations - Lexikon.  Third edition of concise reference work published by FA Brockhaus. These are volumes A & B.  The front and back covers are in tact and feature a decorative impressed scroll design and pattern. The closed book pages feature a slight marble pattern. The pages are all in tact, no tears etc. but definitely aged and darkened in color.  Dates are 1879 and 1880.  10" by 6.5". Illustrated. So wonderful!
