MLO - 1935 Sept. 20 - This is a front and back view of an advertising postcard sent by a pest control company in Harbin. The card entered the postal system on 20th September 1935 and would have been a local item. A local rate postcard at this time would have required postage of 1f but this postcard only has one 1/2f stamp. This probably indicates that this was the local charge for printed matter and if so this rate would have been introduced from 1st March 1934.
