Dear Laura,

Thank you for your help and patience.

The presented object appears to be a silkscreen or serigraph print on paper with 26 x 26 inches measurements. The print has the title"Folklore Planetarische" and was made after Victor Vasarely.
Sadly no additional information for an artist with this name fitting in style and motif is given by reference books and databases.
Comparable objects were recently offered and sold on the international auction market.
This piece is in good condition and no severe damage is visible in the images provided.
A fair market estimation would be between 200 to 400 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards,
Gregory
