On Charles Darwin street in Puerto Ayora you will find some stores that sales mainly figures make out of wood , and jewelry, as there is not many elements they can used or authorize to bring from mainland , there is a nice store name Aymara but they sale very few products from Ecuador or Galapagos , they bring things from Peru and other parts of South America and you can imagine prices are high.
the art scene in Galapagos is nascent. The population is small, many are first / second generation immigrants from the mainland with more of a frontier attitude to earning a living. But things are picking up. I'm proud to say that my little company, CNH Tours, has been highlighting and supporting the art and work of Magno Benett for 15 years. We use his art on our website. Magno has gone from being a lone / struggling artist with little community support, to a recognized community leader during that time (we had very little to do with that). He has been a longstanding promoter of the arts among the youth of Galapagos - so much so that we was appointed as the head of the Galapagos culture centre during the last administration.
A few years ago, we commissioned 7 pieces from Magno and had them hung in the hotel we used. Guests could buy the art, and he would replace it. They are rather large pieces (I have 2 in my home), about 5ft x 2ft. For the story and sampling of his works, see: https://www.cnhtours.com/news/2019/3/22/magic-realism-wildlife-art-cnh-tours-commissions-magno-bennett/
During COVID times, those 7 pieces are hung in the office of the Sulla Travel Agency, a small agency on a Puerto Ayora back-street. They are available for purchase. Ask around and people will tell you how to get there.
