Description

1200 dpi scans:
Unused is defined for this listing as never mailed.
My grandfather was living in Brazil in 1907-08.  Postcard was purchased then...and kept in a postcard album for last 109 years.
Photos likely taken in 1905/06.
Typical yellowish age discoloration (including darkened album strap band imprint on front side...all 4 corners).  Right edge center has stronger yellowing effect (see scan).  Slight emboss effect in each corner due to straps.
Cannot combine with any other shipments due to postal one ounce weight constraints.
