First is a great RPPC of the 1918 Camp Devens team which was captained by Hal Janvrin, who was with the 1915 and 1916 Boston Red Sox World Championship teams. Light crease in upper right no staining, very nice image.
Next is an RPPC of unknown soldiers playing and watching baseball at an unknown camp from the WW1 period. The card was published in Chattanooga Tenn so the encampment could have been local to there.
Best offer in cash or trade takes them. I would prefer to keep them together but would entertain offers separately as well.
