I have added some new links to the right sidebar about dating postcards. One area that many people want to know more about is how to determine the date of a postcard image.
The Curt Teich Guide is extremely useful. The Teich cards were numbered and if you know the
number key than you can date the card with some accuracy. Postmarks may not always be useful when dating a card since the image on the front of the card may be old but was stamped and posted at a much later date.
Certain things in an image may be helpful in dating the card, including cars or automobiles you
can spot in the image, billboards with dates in the advertisement (for example, the introduction of the 1957 Chevrolet), and movie marquees (Ben Hur was showing in 1959), etc.
If you are selling your postcards on an online auction site, it is probably a good idea to put
these in your description since many collectors may look for movie-related items, or automobile
Also check out the new links for dating Real Photo Post Cards (RPPC). These can often be a little
trickier when dating since many were not sent or they show images of people and houses. Some helpful reference books for your home library might include books about automobiles (often issued for a decade of cars, for example cars of the 1960s) or fashions of different decades. Remember, if you are selling your cards, identifying a 1959 Corvette, or Gothic Revival architecture, might make the difference between not selling or selling your card. Be descriptive!
