3c Rose, B. Grill (82). Rich color in shade of 1868 printings, centered to upper left as are all four known examples, fancy cork cancel of Mason Tex. and part of red cancel at bottom, clearly-defined grill easily visible from the front of the stamp
The distinguishing characteristics of the true B Grill are its size–22 points wide by 18 points high (18 x 15 mm)–and the points-up orientation of the grill, which shows as a pyramidal (male) grill impression on the back. The four recorded 3c B Grill stamps were discovered in 1969 on a cover mailed in February 1869 from Mason, Texas, to Germany.
