Mike is correct, it is Publication 461 (the ticket says 'Pub 461'). From what I can see the Brochure is undated, but 460 (just about to be added to the web site) is dated 1st January 1925. so I would expect 461 to be 1925 as well - though there is not always total correlation between Brochure numbers and the date they are published....
