This big guy is painted on a 16x20 double primed flat canvas panel. I used the best quality grumbacher oils on this to give him his realistic look. he will come signed and dated by me, Janelle Dixon on the front and back. He is ready to frame, and would make an excellent decorative item or christmas gift. If you like St bernards, you will love this! The picture shows the painting slightly darker then what it is in real life.
