I have the same
The first poster has text at the bottom of the poster : Mercedes benz Publikation um 1920. Nothing written on the back of all posters.
The second poster has nothing written at the bottom and the third poster has Daimler Benz AG, Stuttgart-Untertuerkheim. WAM 6705-0029. 00-00/1185 Printed in Federal Republic of Germany./Imprine en Republique federale d Allemagne.
Dimensions are approx 60cm x 84cm.
they look the same so could the statement be true about the price
Thank you very much for the updated information! You appear to have original promotional posters pre-WWII era and in reasonably good condition. All have about the same market retail value, which is around $750 to $1,500 each--yes! They are very, very rare--asking prices can be over $3,000 for some so it would be in your best interest to perhaps consult a premier ephemera auction house such as Heritage in Dallas or Cowan's in Ohio. I cannot be absolutely positive they are indeed originals as I can't see them in person, but all the specifications match. If original, the lowest number each would be around $500...for sure, worth looking into further!
