“Nice collection - How do you know the lead Brontosaurus is from the 1930's? I have it too, and have wondered when it was made. I've little doubt it is pre-1959, but know little more than that. It also exists in chrome, by the way. See commented item ”

“Thanks! I have 2 of these, both were purchased in antique shops in Pennsylvania. This one appears to have the original paint - the other one had been painted over. Neither of them have any markings on them at all. I have seen these on ebay with the word Sinclair on the base of the tail - other than that these are exactly the same. I thought maybe it was some kind of local thing in PA. But when I got the book Dinosaur Collectibles I contacted Dean Walker and he told me that this was made by Sinclair in the 1930s. Other than that I can't find any information on them. Do you think they were given away free at gas stations? I wonder if they are from the 1933 World's Fair. I've seen Messmore and Damon souvenirs from the fair and know Sinclair had an exhibit, but I never saw Sinclair toy souvenirs from that fair - surely they would have wanted to compete with The World A Million Years Ago. This figure must look pretty cool in chrome! See commented item ”
