All of Robert Goodin's postcards are printed on actual wood and can be safely mailed with a standard postcard stamp. They are also very durable, will not break, use less wood than a paper postcard, and the wood is sustainably harvested. The grain will vary on each card. They measure 4" x 6".
"Pentapus and Dog"
The grain on this one is rather faint, but don't be fooled, it's printed on a thin sheet of aspen wood. It's Pentapus and his pet dog, Dog. I'm not sure what he's reading. It may be upside down for all I know.
