Information on Bostonian logos would be useful. I just picked up some Bostonian PTH and could recognize it by some of the stitching and the arrangement of the size and style lettering. The insole had a VERY faint log that included "IAN" that helped lead me to conclude it was Bostonian. It was certainly a different logo than seen on @MattRiv shoes seen earlier.
I don't have much info on Bostonian logos. I have a couple old Bostonian catalogs but they are from the 1960s. The color on @MattRiv PTBs looks great.
