Collected by my family approximately 50 years ago and stored in a stamp stockbook ever since. I do not know the source or country of origin. Please refer to the photos for details. They are relatively clean and in good condition for their age, having been stored in a stockbook. I haven't counted them exactly, but there should be about 110 stamps. They will be sent together in a clear plastic bag via postal service (as I no longer have the stockbook). Some stamps may have yellowing or staining due to long-term aging. Please understand this.
