Not looked into American Civil war recruitment/propaganda posters so it was a nice suprise to find these on a War forum. Judging by the poster money was a big incentive to sign up. Most of the men one assumes were from poor backgrounds and $13-$23/month + bonus and $100 when its over was good enough to swell the Union numbers sufficiantly.
Confederation side this time but alone the same lines as the Union poster. $25 clothes allowance and $50 sign up bonus makes it sound appealing for the mid to late 1800's. Touring public meetings to induce men to sign up was a standard event.
