Foster is a slab serif from the Antique category with rather naive proportions for some of the letterforms. Personally, I think its idiosyncrasies lend this face a certain charm, and I’ve always thought Foster seemed a more contemporary design. It was first released in 1905 as metal type by the Inland Type Foundry, St. Louis.
Unfortunately, this is the only capital I in a font of caps and figures. Both sides of the block (not shown in the pic) have been sawed off, and the splintered wood at the junction of the stem and the baseline serifs suggests this sturdy fellow has undergone some character adjustment. I strongly suspect he led a previous life as another letter.
