Photo above from 1972. As I know now he (I mean the monument) lives in Grutas park.
Here is my collection what we lost in the last 30-40 years too :))) This collection I found at various places: Kaunas county public library online resources, Pleskaciauskas archive at epaveldas.lt, etc.
Photo from 1980:
This photo from 1975:
Probably some "very important event" :))
This monument lived in Kaunas 7412 days. On 1990-09-06 this monument finished its life here (from atmintiesarchyvai.lt):
On that day:
This Lenin monument was built in 1970 but even before we had another Lenin . But it has significant drawback - serial production :)))
Another loss - bust of Dzerzhinsky (again serial production) :))
Several more "losses":
Very big "loss": red stars on ST. Trinity church belfry:
And how to live without such wonderfull sign on Ressurection church:
Another "loss": once was official version that this tank IS-2 first entered Kaunas in 1944-08-03. Historical fact: tank was produced in 1945 (how it managed to be here in 1944 still unclear :))))
What a slogans we lost :) As I understand slogan has Russian grammatical errors :))
And what an amazing demonstrations we lost too :)))
Another type of "loss": photo made in Kaunas 1993-08-31 by Požerskis. They are the last group. Dates 1939-10-31 - 1993-08-31:
