I have to confess that among the resources that we can download from the net to help us in our designs, the aged paper texturess are one of my favorites and today I found a truly amazing compilation.
In Design Resource Box they have titled this compilation as "The best collection of high quality aged papers" and I assure you that although the headline may be somewhat exaggerated, if it is not the best, it is undoubtedly one of the best collections of aged paper textures that I have seen in the many years that I have been browsing the net in search of resources for design.
You can download each of the papers and packs of papers from the original article in the source link that I leave you below.
