This is an 16 inch by 16 inch original oil painting on cradled birch wood panel.. I use professional grade oil paint and it's sealed with a Gamvar Varnish (UV Protection and Museum Grade). The painting comes professionally wired and ready for hanging. I ship via USPS priority mail, insured and with tracking. I carefully wrap the painting in archival paper and several layers of thick bubble wrap. Thanks for taking a peek and let me know if you have any questions at all.
