Agenda control, NYC, early 1930s

I was going through old photos and found this. It is from Shaw’s (1954) History of the New York City Legislature. What do you see in it?

Here is the text not baked into an image:

…the legislature’s deliberations. The machine Democrats were visibly perturbed, but with less than 10 per cent of the seats the Socialists were almost completely stymied. B. Charney Vladeck, a Socialist leader, found the only way to get his bills passed was to have a friendly Democrat sponsor them. (Peter J. McGuinness, the famous Brooklyn alderman, once made Vladeck this offer: “Cheeney, if you got something you want to slip through here, just give it to me, old pal. I’ll make it Irish for you.”)
