G. Manetti Boulevard Painting

I have a older oil painting on canvas that belongs to a friend of mine. It was given to her back in the 1960's. The painting itself is 30" X 15". It is in a frame. The content of painting is very busy. Hence the name of it, Boulevard. There's a tag (looks like a receipt) on the backside with lots of information on it. The information is in Spanish and reads as follows..

Nombre de la obra.    Boulevord

Autor.  g Manetti

Nacionalidad.  Y Soliano

Fecha y lugar de nacimiento.   Novora  3-12-21

Estudios.  Escuela de Arte ole Verona

Premios.  Medulla Oro Nacional ole Brencia

There are also 2 different stamps on this tag. One is very faint. But, it reads 

"Made in Spain" and the larger and more legible stamp reads "Registrado" with the registration number of 098365 with Spain at the bottom of this stamp. Any information you may find or if you can give us an appraisal, we would be forever grateful. Thanks in advance. Diane
