This is a folky painting of someone's favorite St. Bernard dog, circa 1870's or 1880's (ONE OF TWO SUCH WORKS IN MY SHOP). Measuring 21" by 16" on the original very old stretchers and 12 1/2" by 12 1/2" (and 17 1/2" by 17 1/2" as framed), the painting is a sweet and classic rendition of a treasured pet of the Victorian era. Vintage dog paintings are very popular and collectable. This one has evidence of its great age, with a darkened surface, no varnish, soil/blanching, very slight stretcher bar show-through at top, and some flaking especially at bottom left as shown. These notwithstanding, the piece is very appealing.
