1929 Panama Canal Zone perf error cover plus 1933 pair on canal postcard to UK

Description

Here we have an unusual perforation variety, probably from a miscut booklet pane, on a 1929 Canal Zone cover plus a pair of stamps from the same set on a Canal Zone locks postcard sent to England in 1933. They have minor bumps, etc., from postal handling. The 1929 cover is quite roughly opened but this does not affect the stamp.
1. A two-cent red Goethals stamp with an imperforate margin to the right and part of another stamp. The right side of the piece is cut straight but the portion of the stamp is slightly wider at the bottom. The item is also imperforate at the bottom.
The stamp is quite likely from a miscut booklet pane, which would explain why the stamp is imperforate at the bottom.
The stamp is tied by a Balboa Canal Zone machine cancel of Feb. 3 1929. The small cover is addressed to one Horace A Carter 2nd, Kinwadin (sp?) Road, Waban, Massachusetts. The sender was Barbara Mitchell of Fort Armador.
The chances against finding such a stamp on cover, even if faulty, are astronomical.
2. A pair of one-cent Gorgas stamps on a picture postcard of the Gutun Locks to London. The stamps are tied by a Cristobal machine cancel of Nov 2 1933. The message is of season's greetings. The IL Maduro Jr. card pictures a warship in the locks. It is numbered 115360.
Canal Zone usages to the U.S. are fairly common but ones sent overseas are not nearly as easy to find.
A highly unusual pair of Canal Zone stamp usages on cover or postcard.
The postage on this lot is higher than I would like, which is down to Royal Mail rates and other charges beyond my control such as eBay and PayPal commissions. I use good British stamps to send all my lots and these should result in collectable stamps cancelled by hand in my village post office for the buyer.
As I have some fixed-price listings, anyone who makes a purchase might want to look at them before paying. If you buy more than one item, please wait for my invoice so I can combine postage.
When payment is received by teatime British time (it is usually dished up about 4:30) I normally post the item the next morning -- as long as payment is made within three days. Our village post office is closed on Saturdays, however, so if you pay on Friday the item cannot go out until the following Monday.
