I just love these tall and narrow 19th c. alphabetical ledger indexes, which served as guides to much larger account ledgers. And the blue hand-marbled cover on this one is especially lovely. With stamped letters on the tabs in black ink, in an unusual font. Not surprisingly, the "Q" page is blank, with other pages ranging from nearly empty to nearly full.
11 15/16" x 3 3/4". One page per letter. Good condition, with binding holding and all pages present, just general wear.
