Day Cycle Company Glued Perfs 1916

Thought I would show this, looking for thoughts on this cover. First glance, I thought no big deal, until I noticed no printing of the image across the perfs. Then I got to looking closer, and you can see a ridge where the perfs are against the stamp. I look closer and you can see little touches of glue. I wonder, why someone would glue perfs, maybe this was a imperf stamp and they were afraid the post office would think it was a forgery? Or maybe sales were slow that day, and the sender had nothing better to do. What do you think?

Part of a coil paste-up.

new to the hobby, can you explain paste up

Nick, there is a glossary button on the upper left side of this page. It explains "paste-up",

So back to the reason there is no cancel ink near the paste-up. The paper on the top part of the paste-up is not level with the lower portion thus forming a small "step". The cancelling device was unable to strike that section. A paste-up on cover is a nice find.

Thanks for all your help, new to the hobby and site, boy I am learning a lot!!!!!!!
