12" wide by 14" high - Brutalist style art piece depicting 2 shore birds.  Art is done with various sizes of nails and tacks with other found metal objects on a green vinyl covered piece of wood whose sides are spiked with forged nails.  I found one other and it was listed on eBay and had a signature of Pina L., not sure if the same artist did this one since it is not signed.  I can say that this one is in much better shape since the nails have not rusted.  The other one looked to have been left outside, whereas this one looks to have been better protected.

The style, color of the vinyl, and overall Brutalist aesthetic scream 1970's.  This was probably retailed at a high-end furniture or decorating/gift store.  Quality piece with one flaw, one of the triangular hanger clips on the back is broken.  It can be replaced, or one could just add a saw tooth hanger bar or even just string it with wire to hang.  Personally, I think it would display best on a table-top style easel.
