Congrats John! Great image..but more than that, it is a hard earned sale based on a great plan. You did everything right on it. Put the time in at the flea markets (not great conditions but you persevered), got your name out, made a contact, made some great art based on a request, and in the end, made a sale. On top of that, you never know when this item will sell again to others or when the buyer will come back to your site for more work...commisioned or otherwise. Finally, it will hang in a studio whee others will come in to see it and possibly be sent your way! Job well done!
