This is a mighty collection of poster templates and flyer templates. All of these are free flyer templates in PSD but you’ll have to reach source page to download them. Since this is a big collection, gathered from various sources, we cannot provide an all-in-one pack as we usually do in other resource posts.
All these files are PSD so you can open and edit them using Adobe Photoshop. I believe most of them are made using older versions of Photoshop so if you own anything above Photoshop CS, you should be able to use all of them.
This is a mixed collection, most of these are party posters of flyers, but there are many other types of PSDs as well.
UPDATE: This post was one of the most popular template collections that we have ever made. Recently, we noticed that the content was getting a little older so we have updated this post. We have added lots of new templates, deleted the non-working ones and the post is a good new one now.
