IV Concurso International Musica Cidade do Porto 1987
Membro de juri Luigi Mostacci
Evidently it was a souvenir given to the judges of the competition. I expected to find a Portuguese hallmark, and indeed the hallmark seems a mix of hallmarks of the city of Porto (the eagle mirrored and placed over the 835) But I did not find this exact hallmark in any text. Someone can give me information.
Thanks in advance
Amena
