I've seen Julia Haack's work around town before. Maybe at 4Culture?. Anyway, these are smartly constructed wall sculptutes, created with recycled wood and latex paint . This example, Operra is 61" x 40". While these appear to be painted shapes, perhaps masked off with tape, however, they are put together like marquetry of perhaps cut tile. Very well done.
I did not catch the title to this example.
Cantinas gives you an idea of the scale of this, the largest of the pieces installed.
A fresh and unique style and presentation that I thoroughly enjoyed. Here website is here.
