I discovered it cost the same to ship an envelope from me (Alaska) to him (Norway) no matter how full it is. He asked me to send him a reprint of an old magazine so since it will cost me the same regardless and the customs declaration form has spots for 4 items I included as declared:
One sketch of a fox valued at $0.03
One sketch of a fuzzy bunny valued at $0.07
One sketch of a sprouted potato valued at $0.37
I really hope someone on his end asks him what the hell? It would amuse me to see his responce to my randomness
