Hi
@Karinhi
You may have seen some of Marc Heffner's artworks and products in Santiago. Here is a link to his website where you can buy greeting cards online. They are not the most inexpensive, but I like his work very much - though they may not be to your taste. I usually buy a few of his greeting cards if I see them in SdeC. If you like these you could contact Marc to find out who is stocking his cards in SdeC and possibly elsewhere on the Camino
I came to know Marc after seeing a print of a one of his artworks in an albergue on the Frances in 2013. I took a photo of it and eventually 'tracked him down' and we have had an irregular but continuing correspondence since then. A few years ago he kindly gave me permission to use one of his lovely artworks as the homepage picture on my blog for the Camino de Madrid.
Since I first came in contact with Marc his range of 'merchandise' has expanded considerably - no doubt there is demand for these souvenirs with increase in numbers of pilgrims since that time.
I have a couple of Marc's prints hanging at home now, which he sent here to Australia in a cardboard tube. In my experience, his delivery arrangements and charges for postage are very reasonable.
Best wishes
Jenny
