Dear Claudia,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a facsimile painting on velum after the medieval Codex Manesse from the end of the 14th century (https://en.wikipedia.org/wiki/Codex_Manesse). These facsimiles were made in the middle or second half of the 20th century.
The first velum shows the famous depiction of the signer Thanhäuser: https://digi.ub.uni-heidelberg.de/diglit/cpg848/0523
The second velum shows Ulrich von Lichtenstein: https://digi.ub.uni-heidelberg.de/diglit/cpg848/0469/image
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 100 to 200 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,
Georg
