Illuminated Ancient and Modern Alphabets - Unknown Author - Unknown Date

This mystery book is among the finest in my possession. There is no author listed, no date of publication, and it appears to be three books in one, with three separate title pages. The first section is replete gorgeous full color and gilded illuminated initial letters. The second is filled with ornamental alphabets, and the third has another grouping of more standard and practical alphabets with a few surprises thrown in. My best guess is that this was a compilation of some of the best material of the era which I assume to be 1860's-1880's judging by the content.
