This blotter sheet was commissioned by Thom Lyttle in 1994 for various psychedelic pioneers to sign. Today, unsigned sheets are harder to find. The printed area of this blotter measures 7.5 by 7.5 or 30 squares by 30 squares. That makes a total of 900, 1/4 in. squares. There is a 1 in. border around the entire blotter for signing room!
