Mounted the large India ink brush tracing of “May, 9, 1917” – (I have practically solved the difficulty of mounting such large tracings, by first immersing them completely in water, then laying it on a previously arranged newspaper mat, on a large cardboard, then lifting it to the table, and smoothing it out with a large “dry” sponge).
