Ode to books

What's he reading? I haven't actually stopped by to look and see if
anything is "written" on the cover of his bronze book. What could be
more appropriate as a landmark for the Monrovia library than Mark

always do a double-take when I walk past. He just seems so real from
the corner of my eye...!
