Some of you have asked where you can see Mary's etchings if and when you are visiting Spain (I have just now realized that there are some comments! thank you!! - I learn and see something new every time I go on the site).
Mary is at the market in Puerto Banus (Nueva Andalucia) every Saturday from 9:30ish to 2 pm. It is a huge market and she is at the top of the hill in the shopping center area where there is an underground parking and a supermarket (SuperSol). Mary's stand is located in the center (of the shopping center) across from the gentlemen who sell the Panama hats. Another option is to give her a call and come by the studio to see her work. The phone number (dialing in Spain) is 95-248-60-35 ( add a 34 at the front if dialing from outside the country).
If none of that works and you have something specific in mind, I can email you some pictures in the theme you are looking for - yes, I know, where IS that website??
Thanks for the comments - keep them coming, now that I know where to look for them!
