[Az-Geocaching] Sig item questions

[Scott Wood]

With Ann and I just now getting back into geocaching after a many year 
break, we are trying to decide on what we want to use as our "signature" 
items.  Many of you will remember the keychains from years ago, (I 
actually found a couple more recently while unpacking) but we want to do 
something different.  I am thinking about combining my photography with 
the sig items.  There is a company called Moo that makes these great 
little cards with your pictures printing on them.  I have online 
galleries of some of my work, and I offer prints for sale there.  Would 
it be out of line to include a link to those galleries on the Moo cards 
that I leave in the caches?  The purpose would not be to sell prints, as 
that is not the purpose of the galleries, but to share my work.  Of 
course selling a print every now and then helps me pay for the hosting 
of the galleries.

I don't think I would be asking this if I was trying to make a living 
from selling prints, as that would be a commercial thing.

Any thoughts?
