GUARDIAN ANGEL, done in egg tempera, natural earth pigments and 24K gold leaf, at St. Mary's Orthodox Cathedral school for iconography, NE Minneapolis, MN in October 2013.  The board is solid ash? imported from Russia measuring ca. 13" x 10" x 1 1/8" routed out and coated with marble dust gesso.  My instructor was Dimitri Andriev.  Est. time to write this icon is ca. 55 hours.  To get an idea of the price, call up your plumber or electrician and ask them how much a job lasting 55 hours will cost, then add ca. $200 for "parts" (gold, pigments, board, etc.) :-)   Then, call me or send me an email and we'll discuss terms - remember we have to allow for drying time so the total time from order to delivery is about six weeks.
