Hello!
I don't really share any replicas here for multiple reasons. But I thought I could share a few of those smaller, less recognisable pieces. I mostly go for screen-accuracy. So these are very close/almost the same as originals.
One of the posters that were on the walls of Diagon Alley and Knockturn Alley in the Chamber of Secrets.
As seen here:
I tried to match the distressing of another copy of that poster that I've seen that wasn't printed super well.
A product label from the Chamber of Secrets that you can see in the Hagrid's Hut. It was then reused in the later films, most notably the Half-Blood Prince.
A bit more on an unusual side as it's just another set dressing prop like that poster. Not specifically designed for the film, but more of a found old design. Still a cool find.
Some of the Honeydukes cellar containers from the Prisoner of Azkaban. Printed on a yellowish paper and aged.
The Knight Bus logo.
The Honeydukes Express label that you can see in the carriage scene in the Goblet of Fire.
The Potions homework sheet that was done originally for the Order of the Phoenix and then used on the later films.
Back and the front of the Knight Bus instructions that Stan Shunpike reads to Harry in the Prisoner of the Azkaban. Not a very well known prop. Quite small prop, maybe 4 cms width?
Some labels.
A poster you can see by the Mulpepper's shop in the first and second films.
No need to introduce this prop. The texture in the back is not really accurate but the text is.
One of the alcohol labels created for the Half-Blood Prince. Still got to replicate the back label, but the front is done.
Again, I'm not really sharing any of the major things for multiple reasons but some of these I hope is of use to anyone (not commercial though).
