"Most of the paintings on this blog will be postcard-sized oil sketches (I call them Postcard Paintings.) I paint them on site, using a modified cigar box as an easel. Occasionally I may post a larger, more finished painting, in which case I'll include the dimensions. If you would like to purchase a Postcard Painting, they cost $100."
And guess what, most of the paintings are quite good and Mr. Keiser has practically sold all of them. Brilliant use of the power of the Web marrying to a forceful way to keep creating on a daily basis.
