Personally, i see no problem with carrying extra paper in case you
run into an image you would love to stamp, frame and hang on your
wall. as long as it doesnt turn into financial gain. then it gets
into this whole copyright mess, and this is a fun non-profit thing,
and yada yada yada...

i am an artist. i made an image i was terribly happy with and made a
bunch of prints before i planted it. to sell. and then i thought
about it. if they arent willing to do the legwork... and it's not
fair to the people who are... so i made more images specifically to
sell. AND I DIDNT SEE ANYBODY AT MY ART SHOW! so i have all these
images matted signed i really dont want to throw away... i guess i
shall cart around a few hoping for exchanges. to anyone who has
already seen the ov box. uuuurg. by the way, i am a packrat and it
pains me to throw away anything. or email me or something. i just
wanna know that you hit the box first.
have fun
