Do you recognize the type of the following Sonnet?

Of Possessions and Clutter

Three possessions, all buried deeply

in layered mem'ries, too much dust.

To sacrifice would not come cheaply

if left to thoughts I cannot trust.

If clutter's value could be measured

whose expertise would deem it treasured?

A print, a photo, and a book,

my rummage heeds a closer look.

The novel, rare, in good condition,

an abstract print, my brother's art.

A photo captures Mother's heart.

The one to go? The first edition.

Each piece, a hidden paragon,

but truly each was good, now gone.
