Does anyone know Antonio Moreno Garrido? I can't seem to find him/her on the website to thank. Do you think it's Antonio Moreno Garrido in the stamp on the corner? I'm offering an award for any information leading to a proper Thank you for this Mail Art.
And cool, no stamp used. Only in Spain!
So Antonio Moreno Garrido, if you are out there, thank you & best wishes for 2013.
