My grandfather took this photo of professional skaters putting on a show at New York's Rockefeller Center rink in November, 1954. I think the gesture of the sculpture with its arms upheld really works with the skaters. View full size.

This is William Bliss, son of Bill Bliss who is the photographer of most of these new pictures I'm submitting. They lived in San Diego. I'm going to say this is in the mid-fifties. Scanned from the 2.5 x 3.5" negative. View full size

This is probably Yosemite National Park some time in the thirties. Scanned from the 4 x 2½ inch negative. View full size

I'd reckon this is the late 1930s in Yosemite. Yosemite seems to be where a lot of these travel pictures were taken. And I can generally judge the age by the kind of negative it is, which is a larger size than the later ones from the '50s and '60s. But tterrace disagrees on the age:

The aspect ratio of the negs is the same as those in our collection from 116 roll film, neg size 2¼ x 4 inches. A popular Kodak Brownie size that could be contact-printed for snapshot-sized prints. Ours date all the way from 1919 up through 1946. Judging by the clothing here, this seems considerably later; 1960s maybe?

Downtown Larkspur, California in April 1966, still largely as it was when I was growing up in the 1950s. That is, most of the buildings still housed establishments that catered to the everyday needs of the average middle-class family: two grocery stores, a pharmacy, hardware store, garage, variety store, even a roofing company, four of whose red pickups are seen in the center. As just two examples of the kind of changes since then, the garage (actually a reproduction of the original structure, which didn't survive a restoration attempt) now houses a salon and spa, and the grocery store my father worked in is an art gallery. I took this Ektachrome from the balcony of City Hall; it was 58 years old at the time, I was 19. This year I'll be turning 65. I always hated math. View full size.
