My approach was to reference both vintage seed packets and vintage fruit crate labels for inspiration. I didn't follow either of those two sources in a literal manner because for something the size of a postage stamp, both had way too much information. But I needed to distill the packet and label reference to their essence in order to successfully solve this design problem. Also I had to come up with one over-arching color palette, plus one basic design that could be applied to all four stamps.
