Now I see this picture, I remember my personal prehistoric era.
The time when I was collecting bones for a glow-in-the-dark T-rex.
An awesome time. The skull came with the first issue of a dinosaur magazine for only FL. 1,50 so I begged my mom to subscribe to get all the bones... she did. Then the 15 other issues appeared to be FL 7,- per issue (sorry mom). And by the time I got the whole T-rex the skull was not as bright as the tail... nonetheless I wish I still had it!
