This is an AMAZING handmade studio art pottery beer mug/stein from Amused Studios in Maryland.  The mug was made for the Burley Oak Brewing Company in Berlin, Md.  The image features an embossed oak tree and the Burley Oak logo.  It is glazed in a thick navy blue glaze that resembled majolica.  The mug is marks on the bottom Amused Studios.  It is about 6 inches tall and 3 inches in diameter at the base.  It is in VERY GOOD CONDITION!  There are no cracks, scratches, crazing, discoloration or repairs.  There is a small chip near the rim (see last photo).
