These are some inspirations and stamps that I found interesting. The first few are art deco rendered/Great Gatsby themed. Then I started to look up ones with a comic style to them, which lead to some modernism and post modernism.
#3: The third stamp from the left in the top row, the one with the sea horse. It is very art deco and would go with a Gatsby commemorative stamp very well. I like the way it’s stylized. A combination of art style of the one before that and the sea horse would be neat.
#5: second one from the right, top row. Rocky Horror Show. I think it’s a combination art nouveau and modernism. It looks like it’d be hand-rendered, but it looks more modern than art nouveau. I’m attracted to it because of the style of the illustration and the contrasting colors. This would be good for a commemorative comic book stamp. But I wouldn’t be sure of which comic to do.
#11: second one down from the right. I’m not really sure what it is, but I love the stylization and color choices. It seems like the Swiss movement because of the stylization. I just really like it, but it would be a good commemorative stamp towards something like manga or anime.
