Added photos with and without flash. Can’t see a signature. Size is 3ft 2 inches by 2 foot. Would it help if I took it out of frame? Maybe something on back? Regards Paul.

Dear Paul,

Thank you for the additional pictures and your patience. This is a painting made in oil paint on canvas and has measurements of 4 x 2 feet. It depicts a standing nude and was highly probably made as a study in the context of an art academy in the 1930s. Sadly this painting is not signed.
An estimation would be between 150 to 300 GBP.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg

Thank you for your appraisal Georg. Regards. Paul
