Great comic postcard from The Ell Co. of Portland, Maine (#5,030) featuring a dog looking at a keg and bottle of Bock beer with the caption "His Master's Breath". Used with a 9/26/06 Troy NY cancel and a 9/27/06 receiving mark from Mechanicsville, NY. Mechanicsville is a Discontinued Post Office (DPO) having closed down in 1921. Very fine, crisp edges, sharp corners
