Dear Aubrey,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a block or brochure with the title "A System of Physical Culture" by Carl Betz in the fourth revised edition published in Kansas City Missouri in the year 1891.
This piece is in bad condition and there are serious damages visible in the images provided.
A fair market estimation would be between 0 to 20 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
