There'll be slight bit of cross-posting for some of my favorite, but my father and I have been going through old slides slowly over the past year and continue to do so. I've several hundred scanned thus far, both my father's and even more from my grandfather, most of them old Kodachrome which is one of my favorites to scan and clean up.
This is my grandmother on their honeymoon in 1947, somewhere in Utah or Wyoming probably. I'm really fond of this photo.
Another of my grandmother in the very house I grew up in (the house of my great-grandparents) sometime in the mid-sixties at a get-together of sorts.
and one more for now, of my mom at Canon Beach in 1981 - taken by my father with his Nikkormat on Ektachrome if I recall.
