Art is my DRG stickers
One day a customer came in and noticed that the acronym for Daniel Rolnik Gallery looked like the word drug (without the 'u'). I thought that was funny and came up with the slogan "Art is my DRG" and had it printed by two different sticker companies.
One company made stickers for cars, which is where I designed the green sticker on their website. And the other was from Sticker Guy - I just checked the box that said I didn't care about the design and then they sent over a batch of the red and black rectangle ones.
