1940s Dog Law Enforcement Postal Card Set of 2. Addressed to Blair W. Egge, Agent. This set of two government-issued postal cards shows the transition between the 1c and 2c rate at the time. The added 1c stamp has LSB (or a portion of LSB on some sets) punched into it. These postal cards are used only in the sense that they have been previously owned. There are no cancellation marks to indicate that they were ever sent through the mail. Good condition with no tears.
