Many of these pipes can be purchased here. Some can be purchased from my Etsy store.
Some pieces are also available from the Bern Gallery in Burlington, Vermont.
I do not do custom pipes. However, if you have a desire for a particular kind of effigy pipe, please let me know. If I should make one that fits into that general category, I will let you know before I put it up for sale on my site, so you can be among the first to see it.
