(PA-275 G10 SENC) India paper on card. Toppan, Carpenter & Co. New York & Philad. A wonderfully laid out $20 from this rare Pennsylvania bank where both Proof and Issued notes are quite rare. This denomination may be unique in any form as this Proof is the only example we have seen. No examples were found in the 1990 ABNC sale. The design is excellently printed in sharp detail with brilliantly bold inks seen. ，
