The Vac loves old maps. Starting with Maine, this project uses USGS historical topographical maps in the public domain from and applies the following processes: 1) The maps are converted from the USGS formatting of geo-PDF to standard graphic format. 2) During conversion the sRGB colorspace is applied. 3) The maps are cropped where necessary to remove areas of scan/photograph that didn’t include the map itself, namely scanner deck and similar. 4) Where applicable the colors are edited – usually in cases of severe yellowing – to improve readability while keeping as much evidence of wear and tear as possible. 5) In some few cases, the maps are further edited to remove uneven edges and scanner deck colors. This occurs where an edge of a map has been folded under or there’s a curve deformation in the scan. This is not done in cases where the map has a physical hole. For each map, an inversion is also created. Thus, each map has a positive and negative version. If you’re looking at a traditional map, you can find the color inversion of that map by searching the name of the map plus the word inversion. If you’re looking at an inverted color map, the traditional map can be found by searching for the name of the map without the word inversion. After the title, the first number is typcially catalog related, the second is typically the year, and the third is typically the scale. USGS maps are in the public domain, and this map is courtesy of the USGS. All edits, color corrections, and digital work beyond the initial archival scan are done by the Vac of For Maine alone, there were 4064 maps in the historical archives. As such, this project is going to take a while. If you would like to have a specific map converted for print, visit and contact the Vac from there. Let them know what town, state, scale, and other things you would like prioritized. The Vac also does custom map modifications. If you’d like custom text or layout added to a map to reflect a game character, a personal location of importance, “Here there be dragons and kittens,” Or similar, the Vac is happy to make that go for you as well for a price. The price for the edits is in addition to the price you pay for the print here – the Vac prefers to use Red Bubble even in cases of direct sale. -Wetdryvac /

Great shirt

by Jayme-Lin on Aug 30, 2018

The print held up very well through its first few washes and the shirt is very very comfy.


Awesome Shirt

by Jessica on Aug 9, 2018

The shirt arrived and I loved it. Not only did it come in the cutest package, the attention to detail inside the packaging was fabulous. All the little touches brought a smile to my face. The Tri-blend shirt material is soft and the fit of the shirt is great! Definitely will be back to order again!
