Here's an add for The Irish Singer's Own book, circa 1880, just $1.00, but that was in 1880 dollars.

Now, that's what I call inflation.

Seriously, though, it looks like the Wearing of the Green Songbook is possibly a reprint, or an edit, of the Irish Singer's Own Songbook. On my copy, the emblem on the spine is not quite the same as that seen on the second book listed above, but I can't quite make out the lettering. Still, it looks like it could be T. B. N. (Thomas B. Noonan, that is).
