Hi. Again an image would be helpful but a good description of the type of postcard and what the inscription was etc.
Chromolithograph, real photo postcard (of whom), leather, silk etc.
Hello Alma - The 1920's postcards in your album are fun comical illustrated examples, as well as, a valentine and typical chromolithographic example of the time. Illustrated comic postcards are collectible and were popular from the early 1900's through the 1930's, 40's and 50's but have a low range unless they are specific areas of collecting such as African American, related to an important war or event or are signed/identified by a known artist..or are particularly cute. Those examples range from 12-15.00, sometimes 18-20.00, while a general comic postcard has a value in the range of 3-5.00. The valentine is quite common and would be c. 4.00 as well as the funny chromolithograph boy.
There are many postcard enthusiast sites to sell on. Those sites will fetch the highest prices rather than selling them in lots locally. Put "vintage postcards sales" in the search to find many different vendors, Ruby Lane also does a nice job of selling ephemera but I do not know if they buy outright or have sellers attach their objects such as on ebay.
Best wishes, Dori
