On a recent visit to Rochester, NY I noticed this gem of a building. While at first sight it may appear ordinary in its joint profile, further examination under the porch showed evidence of a well done tuckpoint joint, that has faded. there is also some evidence of a colorwash or stain that was applied to the brickwork and stopping mortar and has since faded. Alternatively this could be evidence that the red stopping mortar incorporated a red pigment which has almost completely faded. Only the proper sampling and examination of one of these mortar joints could offer some complete answer.
Also notice the pictures of a limestone foundation with a black beaded joint profile. This building is located behind the tuckpointed prick building. In fact you can see the rear of the building in the last photo.
