This is one of the more beautiful books I've seen in a bit: a folio, 4th edition (1921) of the Missale Cæcutientium, the Missal for the Blind, i.e. hard of sight. These were made for priests whose eyesight was failing. The firm of Fridericus Pustet was known for fine printing and excellent lithography (as seen here on and facing the title-page). This particular copy is in unused, as new condition! I nearly wept and salivated all over it. It's a gorgeous liturgical book.
A few other such missals here and here (these not as stunning, but more affordable).
