Here’s part 2 of the Old Airmail Envelopes – same high resolution scans as part 1. The pack contains 12 images (front and back for each envelope) at around 6000-3500px.
They have nice texture details, air mail markings plus some old stamps and if you want to customize them check out my Old Postmark Stamp Photoshop Tutorial. Leave me a comment or share the post if you like them. Thanks!
