I got this from OlimpBase, one of the most wonderful chess sites on the web:
It’s from his “History of ELO ratings 1971-2001”. The PDF file is from 1967, just before FIDE adopted ELO ratings, and uses USCF ratings. You don’t need to follow the link, as I show a “cleaned-up” version here:

We have a glimpse back in time, showing how dominant the Soviets were just at the time Fischer was to begin his ascent to the World Championship. I believe the comments at the end, copied below, are from Prof. A. Elo:
THE UNITED STATES CHESS FEDERATION INTERNATIONAL RATING LIST: Current Ratings as of June 1, 1967
International grand master active during 1966-7, and some of the more active international masters as listed by the U.S. Chess Federation this summer are given herewith. Numbers are on USCF scale, based on competition with other IGM’s and IM’s.
Amusing that Fischer ties first with Spassky in this U.S.-compiled table although his results against leading Russians have been patchy. His grading could of course be enhanced by his sweeping successes against not-quite-top opposition.
