I know how you all enjoy pics, well here you go.
This cover was addressed to my Great Grandfather who was 19 year old at the time of this cancel date. Believe it or not the 5 pages of various foreign stamps shown here were still enclosed. It seems he, my grandfather, and my dad, did not do anything with them. Now here it is 110 years later, and I'm a little intimidated myself.
Unfortunately they are attached with gummed hinges. Not the type you can soak for a few minutes and remove. And some are not in too good of shape. It doesn't appear that any of them have any substantial value, although I have only identified 6 or so.
Just for curiosity I did try to research the stamp dealer that sent these (C.A.Stegmann)and they don't seem to be in business anymore.
I digitally added the red print to identify the various pages.

Any and all information would be deeply appreciated.
