I did a series of stamps for the Singapore Post office. They are scenes from various wet markets in Singapore. Ballpoint pen + gouache + photoshop touch up. If you like stamps, you can buy them today or down the week at a Singapore Post office while they still have stock.
I gave the vegetable seller his stamp and left him smiling. I gave the fish seller his stamp but he could not see what it was because he didn't have his glasses. He placed them in a transparent plastic bag so the fish guts on his hands wouldn't get on the stamp.
