Itsybitsyoldphotographs

Hi All,
I picked up a small packet of tiny photos this morning at an estate sale. 
It is a three inch by 1.5 inch (guessing) brown packet. ON the outside it says "genuine photographs" "washington cathedral" "Washington DC"
and inside the packet are about 20 different real photos, black and white , of the cathedral.
Is this a collectible? Is this worth the 50c i spent?
Thought it was interesting, and might have some value to someone.
Thanks

I'd say it's wort the fifty cents you spent on it. Especially if you like it. I can't find any references to one yet. I'm still looking. Was it commercially made to sell or is this a homemade booklet?

HI, Thanks for looking!
It was commercially made, and the the little wrapping on the back has a 1 1/2 cents for postage, if no message is written in the little space below!
I thought, hey what the heck....
Honestly, i think i will be giving them away... if given the chance to clutter and hoard, not good! best to return into the world
Thank you!!!
