Box of lantern slides titled 'Selected slides for USA 1969'. These were used by Platt for his lecture tour of the USA in 1969. They cover a range of clinical subjects, including x-rays and photographs of cases of birth palsy, arthritis and pseudo-coxalgia (/1-97). There are also images of orthopaedic equipment and orthopaedic hospitals at which Platt worked (/98-133).
See PLA/10/1/4/5 for Platt's diary of his 1969 lecture tour of America and PLA/12/1 for historical files on orthopaedic hospitals.
