So I've received some starters from Erin Young... and the attention she gave to the back of the ATC put me to think... She used part of the ATC to sign and add the date of creation... so i gave it a try and made a test.
This is the back of some new ATCs... they are a lil bit thicker from my latest ones, that are at the moment traveling or resting at someone's truck. They start somewhat united and then are cut. just a simple detail, just because.
Yes, ... they have the 16.07.2015 as the date i will finish them, because between letting ink and glues to dry...
I've bought a few old stamps from a commercial store, and they were used on invoices and products. These aren't the literal translations since they are old Portuguese terms:
"A 30 DIAS" » "TO BE PAYED 30 DAYS FROM NOW"
"CÓPIA" » "COPY"
"CAIXA" » "RECEIVED"
"FRETE" » "SENT"
