1974 Brazil
tribute to Edgar Roquette-Pinto
design: Aluisio Carvao
A stamp dedicated to the founder of the first radio station in Brazil, called Radio Society of Rio de Janeiro. Cool design of radio waves from a tower – a bit psychedelic yet well controlled.
ブラジルに最初のラジオ放送局を作ったロケッテ-ピントを記念する切手。ラジオ局長は、もともと医者で、のちに民俗学者になった人のようです。70年代のちょっとサイケな色使いが、電波の飛ぶ様子をクールに抽象化しています。

I see that you have a theme here. Do you create themed stamp albums as well? What other themes have caught your eye recently?
Before the radio wave & lattice tower, I had long time theme on hands – more than a year…

Before then, I had kawaii/cute season and print history.
Other themes are on the left hand menu, under ‘topics’ category.
Yes, I have too many themes for stamp collection, but basic way for me is buying stamps when I like them. Even on my ‘theme’, I don’t get it if a stamp is not designed well.
I will definitely look at more of your website and explore more of your themes. Thank you for sharing.
