I bought a painting at a garage sale. It is an oil on canvas of a beautiful old bridge.?

The front is signed NATHAN.





On the back of the painting there is a label.





Certificate of Authenticity


Collectors Corner, Inc.





And it has been initialed and dated four times.





I tried to google them but struck out.
