Thank you for submitting your item for appraisal. This appears to be a set of various family photographs of the 1920s to 1940s. During that period photography was very common, every second child had a kodak camera. These photos would present a high sentimental value for you and your family, but the market value would be low. The photographer is unknown, the motifs are not spectacular, historically there is not much to gain from, except for you and your family. If put up for auction the result would be rather low. Keep it as a family heirloom.
