Flask With Portholes. An antique flask with names etched into its surface, stamped with date, has been altered to admit 3 portholes. Each porthole window is optical lens has been inserted into silver coins that have become their frames. These coin 'frames' are then drilled into and screwed with tiny bolts that must be tightened from within. While the windows are watertight, the ancient cork in the lid does not seal this little sculptural keepsake object.
